摘要:
The thermal behaviour of M(II)(H2L)2.2H2O complexes (H2L- = isoorotate and 2-thioisoorotate monoanions; M = Mn, Fe, Co, Ni, Cu, Zn, Pd, Pt) has been studied by TG, DTG and DSC methods. The thermal decomposition of these compounds takes place in two steps: dehydration and pyrolytic decomposition. The TG and DSC data suggest that water molecules are structurally well defined, being coordinated to the metal ion, with the exception of the Pd(II) and Pt(II) complexes. When possible, the weight-loss effects have been assigned from the IR spectra of intermediate species.
