title: Spectroscopic and physicochemical studies on nickel(II) complexes of isatin-3,2'-quinolyl-hydrazones and their adducts.
abstract: Nickel(II) complexes of isatin-3,2'-quinolyl-hydrazones of the type [Ni(L)X] (where X=Cl-, Br-, NO3-, CH3COO- and ClO4-] and their adducts Ni(L)X.2Y [where Y=pyridine or dioxane and X=Cl-, Br-, NO3- and ClO4-] have been synthesized under controlled experimental conditions and characterized by using the modern spectroscopic and physicochemical techniques viz. mass, 1H NMR, IR, electronic, elemental analysis, magnetic moment susceptibility measurements and molar conductance, etc. On the basis of spectral studies a four coordinated tetrahedral geometry is assigned for Ni(L)X type complexes whereas the adducts (Ni(L)X.2Y) were found to have a six coordinated distorted octahedral geometry.
