Studies on some homo- and heterobimetallic thiocyanato and selenocyanato bridged complexes with 1, 2-bis( diphenylphosphino )ethane

Abstract

A few complexes of the type MM'(XCN)₄ (dppe)₂ (where M = Co²⁺, Ni²⁺, Cd²⁺; M' = Cd²⁺, Hg²⁺; X = S, Se; dppe = 1,2-bis(diphenylphosphino)ethane have been synthesized and characterized by elemental analyses, molar conductance, magnetic moment, IR and electronic spectral studies. The softness parameters <img src='/image/spc_char/delta.gif' border=0>TE<img src='http://www.niscair.res.in/jinfo/equation115.gif' border=0> of the probable and alternative structures have also been calculated to derive the binding site of the thiocyanate/selenocyanate ligand.
