Mixed ligand complexes of the type [Ni(L)(L1-4)2],[Ni(L)(L5)3] [Ni(L)(L6)2,H2O], and [Ni(L)2] where L = 2-mercapto-3-phenyl-4-quinazolinone (MPQH), L1= PPh3, L2= AsPh3, L3= b-picoline L4= pyridine L5 = pyrazole and L6= imidazole are prepared and characterized on the basis of elemental and thermal analysis, electronic and infrared spectral studies, conductivities and magnetic susceptibility measurements. A study of electronic spectra gave evidence about complexation. Shifting in the characteristic infrared absorption bands of the free ligands after complexation indicates the nature of bonding. Thermal data revealed the presence and absence of coordinated water molecule. The molar conductivity in DMF indicates of non-electrolytic behavior of these complexes.
