Involved in Crystallography Research      A Brief Overview

 

 

1. Historical Overview            

 

The first results reported by a Macedonian researcher using X-ray scattering measurements are those of Stefan Pocev of the Faculty of Technology and Metallurgy  (Cyril and Methodius University) in Skopje, who worked (1970―1973) with professor Georg Johansson at the Royal Institute of Technology in Stockholm, Sweden. In 1973, Pocev published in Acta Chemica Scandinavica (27, 2146―2160, 1973) the paper “An X-ray Investigation of the Coordination and the Hydrolysis of the Uranium(IV) Ion in Aqueous Perchlorate Solutions”, followed by a short communication (28, 932―933, 1974) and another paper (33, 179―185, 1979) in the same journal. Later (1978) Stefan Pocev completed his PhD thesis on determination of crystal structure of some mercurated oxonium and sulphonium salts at the University of Zagreb, and the results were published in the Journal of Chemical Society, Dalton Transactions, 2457―2458, 1985.

 

From 1972 through 1974, Gligor Jovanovski from the Institute of Chemistry (Faculty of Natural Sciences and Mathematics) in Skopje stayed as a postgraduate student in the X-ray Laboratory of Professor Drago Grdenić and Professor Boris Kamenar at the University of Zagreb, where he worked on determination of the crystal structure of tetrakis(trifluoro­acetoxymercury)methane, the first example of a carbon atom bound to four mercury atoms in a nearly regular tetrahedral arrangement (J. Chem. Soc., Chem. Comm. 546, 646―647, 1974). Later (1978―1981) Gligor Jovanovski continued the research on his PhD thesis at the same University, where he determined several crystal structures of metal saccharinate complexes. In collaboration with Josh Thomas from Uppsala University, he studied the deformation electron density of potassium oxalate monohydrate (Acta Crystallogr. B43, 85, 1987).

 

After moving back to Skopje in the early 1980s, Jovanovski was the first professor to introduce a course in crystallography at the largest national University in Macedonia, the SS. Cyril and Methodius University in Skopje. The course was included, as a part of the Structure of Molecules major, in the curricula at the Department of Chemistry at the Faculty of Natural Sciences and Mathematics. At that time, only two powder X-ray diffractometers were available in Macedonia—a Jeol instrument, operated by the Faculty of Natural Sciences, and a Philips instrument operated by the Faculty of Technology and Metallurgy. The two instruments were used for routine analyses, characterization, simple experiments and teaching. In the following years, a small group of crystallography researchers was established at the Institute of Chemistry, including Aneta Mirčeva, Orhideja Grupče, Panče Naumov and Petre Makreski. Sporadically, X-ray diffraction was employed for structure determination and characterization by other members of the Institute of Chemistry: Bojan Šoptrajanov, Vera Jordanovska, Vladimir Petruševski, Slobotka Aleksovska, Viktor Stefov, Gjorgji Petruševski and Tomče Runčevski.

 

Until 1989, when the country was still a part of SFR Yugoslavia, Professor Jovanovski has been a regular participant of the Annual Meetings of the Yugoslavian Center of Crystallography, and he also organized one of the meetings (in 1981) in Skopje, Republic of Macedonia. Since 1996 Jovanovski has continuously participated in the Annual Croatian-Slovenian and Slovenian-Croatian Crystallographic Meetings, occasionally together with other Macedonian crystallographers (Stefan Pocev, Vera Jordanovska, Aneta Mirčeva, Orhideja Grupče, Panče Naumov and Petre Makreski). Very recently, a Division of Crystallography was established as part of the Society of Chemists and Technologists of Macedonia, which represents the crystallographers and structural chemist from the country.

 

 

2. Current Condition and Activities

 

At present, owing to the nearly two decades of economic transition, none of the national or private Universities in Macedonia (a total of about ten institutions) operates modern crystallographic equipment. The results of the small group of active Macedonian crystallographers have been obtained either during their research work in foreign universities, or as a collaboration with such institutions. Dr. Panče Naumov and Dr. Petre Makreski, both supervised in the past by Professor Jovanovski, appear as the most promising young scientists that are currently active in the field. The main research subjects of Macedonian crystallographers have been related to chemical crystallography (especially, metal-coordination compounds as models for biological effects of food additives), inorganic compounds (spectra-structural correlations in isomorphous and isotypic series), organic compounds with interesting electronic, optical and other properties, solid-state reactivity (photochromism, thermochromism and related reactions), organic polymorphism of pharmaceuticals, and very recently, minerals that naturally occur in Macedonia. A work on a few projects is currently active, including the preparation of an Atlas of Minerals from the Republic of Macedonia, a monograph which is to be published soon (in English) by the Macedonian Academy of Sciences and Arts.

 

One of the most active research groups of the Division of Crystallography in Skopje (G. Jovanovski, O.  Grupče, P. Naumov) has contributed to the crystallographic research with over 40 publications in renowned international journals, which are mainly related to the rich coordination chemistry of saccharin (artificial sweetener with suspected carcinogenic activity), thiosaccharin and their mixed complexes with aromatic bases. In 2000 P. Naumov moved to Tokyo Institute of Technology, where under the supervision of Yuji Ohashi, he received (2004) a PhD degree in diffraction methods. After forming a new laboratory for study of photoinduced phenomena and solid-state chemistry at the National Institute for Materials Science in Japan (2004―2007), since 2007 he is a leader of an independent research group at Osaka University (Japan). In 2009 Dr. Naumov was appointed Associate Professor from the external staff at the Institute of Chemistry in Skopje, continuing to collaborate with the researchers in Macedonia in the efforts to contribute to improvement of the conditions for crystallography research in the country. The current research interests of the group are related to materials exhibiting photoinduced and thermal phase transitions – promising candidates as future materials for the (opto)spintronics, X-ray photodiffraction and time-resolved diffraction using synchrotron X-rays.

 

As one of the outstanding reported structures from the Macedonian crystallographers, together with G. Jovanovski (Skopje), B. Kaitner (Zagreb), D. A. Rae (Canberra) and S. W. Ng (Kuala Lumpur), in 2005 Dr. Naumov determined the crystal structure of the sweetener sodium saccharinate, Na64(C7H4NO3S)64·120H2O (Angew. Chem. Int. Ed. 44, 1251–1254, 2005), an important commercial compound for which a long time the formula of a dihydrate had been assumed. The extremely complicated modulated structure with a unit cell of 15.6 nm3 and Z′ = 16 (Z = 64) was ranked #6 in the World’s database of small-molecule structures with high Z′ (University of Durham). Another very recent example of the activity of the Division of Crystallography is the first direct observation of an all-solid autocatalytic reaction set, a group of photo-triggered reactions proceeding in the crystals of the natural mineral realgar (J. Am. Chem. Soc. 132, 11398–11401, 2010). There are several ongoing activities aimed at improvement of the crystallographic equipment in Macedonia, and in relation to that, the members of the Division of Crystallography are very open for constructive suggestions and ideas.
