Abstract

The solid-state thermal decomposition of the dinuclear pivalate complexes LM(μ-OOCR)4ML, both those synthesized earlier (M = MnII, FeII, or CoII; L = 2,6-(NH2)2C5H3N)) and new complexes (M = CuII; L = 2,6-(NH2)2C5H3N or (2-NH2)(6-CH3)C5H3N), was studied by differential scanning calorimetry and thermogravimetry. The decomposition of the CoII complexes is accompanied by the aggregation to form the volatile octanuclear complex Co84-O)2n-OOCCMe3)12 (n = 2 or 3), whereas the thermolysis of the MnII, FeII, and CuII complexes is destructive, the phase composition of the decomposition products being substantially dependent on the nature of metal and the α substituent R in the apical organic ligand.
