Sp. Sovilj et al., Thermal stability and kinetic studies of new dinuclear copper(II) complexes with octaazamacrocyclic and multidonor bidentate ligands, THERMOC ACT, 370(1-2), 2001, pp. 29-35
The thermal properties of four copper(II) complexes with N,N',N",N"'-tetrak
is(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and several bi
dentate ligands N,S (thiosemicarbazide and thiourea) or N,O donors (semicar
bazide and urea), of the general formula [Cu-2(X)tpmc](ClO4)(4), have been
investigated by thermogravimerry (TCT) and differential scanning calorimetr
y (DSC). The thermal stability order can be recognized for the examined com
plexes, depending on coordinated bidentate bridging N,S or N,O ligand. Kine
tic data demonstrated first-order thermal decomposition. A plausible mechan
ism has been proposed which explains the major products of the degradation.
