Publikováno v: Journal of Thermal Analysis. 42:973-979

The thermal dehydration of pentacoordinate complexes [Cu(maleinate)(H 2 O)] (1), [Cu 2 (citrate)(H 2 O) 2 ] (II) and [Cu(phenoxyacetate) 2 (H 2 O) 3 ] (III) was investigated and correlated with the structural changes occurring during the dehydration.
