Preparation, Spectroscopic Characterization and Solid State Electrical Conductance of Bimetallic Salts of the Type [M(L—L)3] [M′(MNT)2]. Part II
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.
Synthesis and Structural Characterization of Bimetallic Salt [Ni(phen)<sub>3</sub>][Ni(mnt)<sub>2</sub>] and [Ni(bpy)<sub>3</sub>][Ni(mnt)<sub>2</sub>]
complexes [Ni(phen)3][Ni(mnt)2] (1) and [Ni(bpy)3][Ni(mnt)2] (2) (mnt2−=maleonitriledithiolate) have been synthesized and characterized. X‐ray crystal structure analysis revealed that the compounds consisted of a coordinated nickel cation with distorted octahedral center and a planar [Ni(mnt)2]2−. Due to the different space effects of the cations, compound 1 is crystallized in Pī and 2 in P21/a space groups
