The Cu(II), Ni(II) and Co(II) complexes of ligand (P-ClINAP) P-Chloro isonitrosoacetophenone derived from isonitrosoacetophenone have been synthesized . The complexes of formula Cu(PClINAP) 2, Ni(P-ClINAP)2, Co(P-ClINAP)2 have characterized on the basis of elemental analysis, molar conductance, magnetic data, electronic spectra etc. and their possible structures are discussed. The diamagnetic nature of Co(II) complex indicates octahedral geometry while the diamagnetic and spectral features of the Cu(II) and Ni(II) complexes suggested square planer geometry.
