Abstract

Polymeric chelates of bis(mercaptoacetamido)-1,4-diaminobutane (BMADB) with manganese(II), cobalt(II), nickel(II), copper(IT), zinc(II) and cadmium(II) ions have been synthesized and characterized by elemental analysis, magnetic moment, infrared, electronic spectra and thermal analysis. In the present investigation the ligand BMADB exhibits bis-bidentate character and coordinates symmetrically with metal through nitrogen of amido and sulfur of mercapto groups. The thermogravimetric studies indicate a two stage decomposition and the presence of water molecules. Thermal data have been analyzed by Freeman-Carroll and Sharp-Wentworth methods and various kinetic and thermodynamic parameters have also been evaluated. Comparable values of parameters indicate common decomposition reaction mode in all chelates. Their d.c.electrical conductivity in pellet form over a wide range of temperatures have also been studied.
