| Abstract: | Summary Reactions of glyoxal bis(morpholineN-thiohydrazone), H2gbmth, with NiCl2·6H2O, Ni(OAc)2·4H2O, Ni(acac)2· H2O, CuCl2·2H2O, Cu(OAc)2·H2O, Cu(acac)2, CoCl2· 6H2O, Co(OAc)2·4H2O and Co(acac)2·2H2O yield complexes of the type M(gbmth)], M=NiII, CuII or CoII]. Diacetyl reacts with morpholineN-thiohydrazide in the presence of nickel salts to yield NiII(dbmth)], NiII(dmth)(OAc)]H2O and NiII(Hdmth)(NH3)Cl2] involving N2S2 and NSO donor ligands. Copper and cobalt complexes of N2S2 and NSO donor ligands with compositions CuII(dbmth)], CoII(dbmth)]·4H2O and CoII(H2dbmth)]Cl2, have been isolated. The compounds have been characterised by elemental analyses, magnetic moments, molar conductance values and spectroscopic (electronic and infrared) data. |
