摘要

A solvated form of zinc dimethyldithiocarbamate adduct with piperidine of the composition [Zn{NH(CH2)(5)}{S2CN(CH3)(2)}(2)] center dot 2C(6)H(5)CH(3) (I) was synthesized. The structure and thermal properties of the adduct were studied by X-ray crystallography and simultaneous thermal analysis (STA). The structure of compound I is characterized by the presence of a system of channels populated by solvating toluene molecules (structural type of lattice clathrates). The central zinc atom coordinates two dithiocarbamate ligands and a piperidine molecule (zinc coordination number CNZn = 5). The zinc polyhedron geometry is intermediate between a tetragonal pyramid (TP) and trigonal bipyramid (TBP); the contributions of the TP and TBP components were evaluated from the X-ray diffraction data. The STA study of the thermal properties of I has shown that the weight loss occurs in three steps and includes desorption of solvating toluene molecules, then, desorption of coordinated piperidine molecules, and thermolysis of the dithiocarbamate moiety of the complex with formation of a zinc sulfate powder.
