Abstract

The halide complexes of transition metals with 1,3-dipiperidinipropane of the general formula M(CH 2(CH 2NC 5H 10) 2)Br 2, where M = Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), have been synthesized and characterized by elemental analysis, electronic and IR spectra, room temperature magnetic moment studies and conductivity measurements. The thermal behavior of these complexes has been studied by TG and DTA. All these complexes show two steps weight loss upon heating up to 700°C, with simultaneous loss of organic and inorganic fragments and show almost similar mode of decomposition. Their compositions were confirmed by microanalytical analysis and IR spectroscopy. The residues after heating correspond to metal oxide. Cadmium forms the most thermally stable complex.
