SYNTHESIS AND STRUCTURE OF MIXED LIGAND COORDINATION COMPOUNDS OF COBALT (II) WITH DIALKYLDITHIOPHOSPHATE IONS AND NITROGEN HETEROCYCLE
For the first time, a mixed ligand complex [Co(MAB)(i-ProPS2)2] was synthesized and its structure was studied by XRD phase, X-ray
structural, derivatographic analysis and IR spectroscopy. The participation of dialkyldithiophosphorus and amino groups in complex
formation was confirmed. Based on the structural information, the nature of the interaction of molecules and the methods of their packing
into crystal structures are considered.
