PREPARATION, SPECTROSCOPIC CHARACTERIZATION AND SOLID STATE ELECTRICAL CONDUCTANCE OF BIMETALLIC SALTS OF THE TYPE [M(L-L)(3)][M'(MNT)(2)] .2.

摘要

Complex bimetallic salts of the type [M(L-L)(3)][M(1) (MNT)(2)] [M = Ni(II), Zn(II), Cd(II), Fe(II), Co(II), Cu(II) and Ru(II); M(1) = NI(II) and Co(ll); L-L = 2,2'-bipyridyl (bipy); 1,10-phenanthroline (o-phen) or ethylenediamine ten); MNT 1,2-dicyano-1,2-ethylenedithiolate] have been prepared by the reaction of Na-2[M(1)(MNT)(2)] and [M(L-L)(3)]X(2). These salts have been characterized by elemental analyses, molar conductance, magnetic susceptibility, IR and UV-visible spectral studies. X-ray diffraction patterns indicate their non-isomorphous nature. All the complexes behave as semiconductors as their solid-state conductivities were found to increase with the increase in temperature from 305 to 393 K. [References: 17]
