Complexes of copper(II) with the hydrazones derived by the condensation of 4-methoxybenzoyl hydrazide with salicylaldehyde, <i>o</i>-hydroxyacetophenone and diacetylmonoxime

872-876The reactions of hydrazone ligands derived by the condensation of 4-methoxybenzoyl hydrazide and salicylaldehyde (H2SMBHON), o-hydroxyacetophenone (H2OHAPMBHON) or diacetylmonoxime AMMBHON) with CuCI2.2H2O, Cu(OAc)2.H2O and Cu(acac)2 under varied reaction conditions have been studied leading to the synthesis of many new dinuclear copper(ll) complexes with subnormal etic moments at room temperature. An interesting class of neutral dinuclear diamagnetic copper(II) compounds has also been isolated. The complexes isolated have been characterised by elemental analysis , molar conductance values, molecular weights, magnetic susceptibility and spectroscopic (UV-visible, IR and PMR) data
