Abstract
The reactions of the dilithium derivatives of 9,12-dihalogen-ortho-carboranes 1,2-Li2-C2B10H8-9,12-X2 (X = Cl, Br, I) with mercury chloride HgCl2 afford a number of complexes of the chloride ion with the halogen derivatives of [12]mercuracarborand-4: {[(9,12-X2-C2B10H8-1,2'-Hg)4]Cl}Na·nH2O. The molecular crystal structure of the complex of the [12]mercuracarborand-4 octaiodine derivative with the chloride ion is determined by X-ray diffraction. The substituents at the periphery of the mercury-containing macrocycle are found to exert a substantial effect on the macrocycle geometry leading to the transition from the planar to butterfly conformation, whose geometry is predetermined by a set of intermolecular interactions in the crystal.
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.
