Abstract
The reactions of cobalt(II) nitrate or perchlorate with acetamide (AA) or carbamide (Ur) in an aqueous medium results in formation of coordination compounds [Co(Ur)4](NO3)2 (I), [Co(Ur)6](NO3)2 (II), [Co(AA)4(H2O)2](NO3)2 (III), [Co(AA)4(H2O)2](NO3)2∙2AA (IV), [Co(Ur)6](ClO4)2, (V), [Co(AA)4(H2O)2](ClO4)2 (VI), and [Co(AA)6](ClO4)2 (VII). The compositions of the isolated complexes are determined by physicochemical methods, and the crystal and molecular structures of compounds II, V, VI, and VII are solved. Specific features of the thermal behavior of all synthesized compounds in a wide temperature range are studied in detail. These compounds are shown to be used as precursors in the preparation of nanosized Co3O4 using self-propagating high-temperature synthesis. The catalytic activity of thus synthesized Co3O4 in the model epoxidation of allyl alcohol is studied.
期刊介绍：
Russian Journal of Coordination Chemistry is a journal that publishes reviews, original papers, and short communications on all aspects of theoretical and experimental coordination chemistry. Modern coordination chemistry is an interdisciplinary science that makes a bridge between inorganic, organic, physical, analytical, and biological chemistry.
