Influence of the nature of organic components in dinuclear copper(II) pivalates on the composition of thermal decomposition products

Tetrabridged dinuclear complexes ((2-NH2)C5H4N)2Cu2(μ2-OOCCMe3)4 (2·С6Н6) and ((3-NH2)C5H4N)2Cu2(μ2-OOCCMe3)4 (3) and the cocrystallization product ((4-NMe2)C5H4N)2Cu(η2–OOCCMe3)2·2((4-NMe2)C5H4N)2Cu2(μ2-OOCCMe3)4 (4) were synthesized by the reaction of the polymer [Cu(OOCCMe3)2]n (1) with aminopyridine ligands (L) of different nature (Cu: L = 1:1) in С6Н6. The solid-state thermal decomposition of these compounds was studied by differential scanning calorimetry and thermogravimetry, and their electrochemical behavior was investigated by cyclic voltammetry. All newly synthesized complexes were studied by X-ray diffraction, the magnetic properties of the complexes were investigated, and ESR measurements were performed.
