Zinenko T. Isotrithiondithiolates of transition metals: synthesis, structure and some physical-chemical properties.

The object of research: the influence of the character of transition metal, size of extra-spheric cation and complex anion charge on the physical-chemical properties of the isotrithionditiolates of transition metals Ktn[M(dmit)2] , where Kt-Li,Na,K,Rb,Cs; M- Mn,Fe,Co,Cu,Hg; dmit2-=C3S52-; 0?n?2, and on the their structure. The development of universal principles of the synthesis of compounds this class. Synthesis and examination of features of a composition of complexes and their properties. Synthesis and investigation of the isodithion-on-dithiolates of transition metals Ktn[M(dmid)2], where Kt - li,Na,K,Rb,Cs; M - Ni,Co; dmid2-=C3OS42-; 0<n?2. Research techniques: the element analysis, IR-spectroscopy, polarography with hard (platinum) electrode, measurement of conductivity, quantum chemistry simulation by means of scattering waves (SW X?) method. 60 new isotrithiondithiolatemetalates (dmit) have been synthesized. The increase of the conductivity of the complexes in 4-5 order by decrease of sizeof extra-spheric cation and by oxidation of the complexes has been detected. The causes of big amount of possible structural types for the synthesized complexes have been determined. The stability of isotrithiondithiolatemetalates of sodium in the acetonitrile solution has been investigated. 10 new isodithion-on-dithiolate complexes have been synthesized. The compound Li0.5[Co(dmid)2] is complex of mixed valence. The planar oxidized ferum and cobalt complexes are starting substances for the synthesis of new highly conductive dmit compounds, and manganese, copper and mercury complexes are perspective candidates for the obtain of new photocells and nonlinear optical materials. Sphere of use: chemistry and physics of solid, chemistry of d-element complexes.
