Abstract : Complexes of Co(II), Ni(II) and Cu(II) with Oxalic(Oz), malonic(Mz) and terephthalic (TPZ) dihydrazides have been prepared and characterised from elemental analysis, magnetic moment, visible, IR and ESR spectra. Based on this data a polymeric octahedral structure has been assigned for the MCl/sub2/ L.H/sub2/O complexes and a sulphate bridged four coordinate polymeric structure for the CuSo/sub4/L.H/sub2/O complexes. TGA and DTA results are also reported.
