PHYSICO-CHEMICAL STUDIES OF SOME MIXED LIGAND THIOCYANATE COMPLEXES

Abstract

A characteristic feature of the d-group transition metals is their ability to form complexes with a variety of neutral molecules such as carbon monoxide, isocyanides, substituted phosphines, arsines, stibines or sulphides, nitric oxide, various molecules with delocalized ir orbitals, such as pyridine, 2,2'-dipyridyl, 1,10-phenanthroline and with certain ligands containing 1,2-dithioketone or 1,2-dithiolene groups, such as dithiomaleonitrile anion. Certain platinum metals can also form complexes where the trichlorostannite ion, SnCl" , is a ligand. .......................
