Tetra-µ-acetato-κ⁸O: O'-bis [(3, 5-dimethyl-1H-pyrazole-κN²) copper (II)]

摘要: The dinuclear centrosymmetric title compound,[Cu2 (CH3-CO2) 4 (C5H8N2) 2], has a distorted square-pyramidal coordination geometry around each CuII atom in which four O atoms from the bridging acetate ligands form the basal plane while two N atoms from the pyrazole ligands occupy the apical positions. The crystal has two half molecules in the asymmetric unit with a CuÁÁÁCu distance of 2.6762 (4) A. Disorder was found for two O atoms and two C atoms of one acetate ligand and refined with occupancies of 0.265 (7) and 0.735 (7). The crystal also features molecules linked through two N—HÁÁÁO hydrogen bonds resulting in one-dimensional chains extending along the crystallographic b axis.
