The complexes of Cu(II) with Schiff bases viz Bis (2-hydroxynapthaldehyde) malonoyl dihydrazone (BNHMDH), 5-Chloro salicylaldehyde isonicotinoyl hydrazone (SIH) and 5-Chloro salicyladehyde morpholine N thiohydrazones, (SMTH) are formed. The schiff base BNHMDH was formed by 2-hydroxy napthaldehyde and malonoyl dihydrazone, SIH was formed by 5-chloro salicyladehyde and isonicotinoyl hydrazone and SMTH was formed by 5-chloro salicyladehyde and morpholine, ESR, electronic and infrared spectral studies and electrical conductivity data suggests square plannar geometry.
