The thermal behaviour of SnP2O7 and PbP2O7 were investigated. The tin compound is stable at least at temperatures up to 1150°, whereas PbP2O7 begins to loss oxygen around 400°. The spectroscopic and roentgenographic analysis of the decomposition product, shows that it is the known polymeric lead(II) metaphosphate.

Abstract  

Complexes of Cu(II) with substituted o-acetoxy benzoic acids (5-haloaspirines, X-asp) with and without pyridine (py), of composition [Cu2(X-asp)4] and [Cu(X-asp)2(py)2 ] have been synthesized and characterized. Electronic and vibrational spectroscopic data of these complexes are reported. Its thermal behaviour was investigated by thermogravimetry and differential thermal analysis. In all complexes, the haloaspirinate ligands decompose in two or three steps, starting with the break up of the coordinated acetoxy groups. CuO is obtained as the final pyrolysis residue in all cases.
