Tetra-μ-acetato-κ(8) O:O′-bis­[(3,5-di­methyl-1H-pyrazole-κN (2))­copper(II)]

The dinuclear centrosymmetric title compound, [Cu(2)(CH(3)CO(2))(4)(C(5)H(8)N(2))(2)], has a distorted square-pyramidal coordination geometry around each Cu(II) 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 ap...

Sumario:The dinuclear centrosymmetric title compound, [Cu(2)(CH(3)CO(2))(4)(C(5)H(8)N(2))(2)], has a distorted square-pyramidal coordination geometry around each Cu(II) 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 Cu⋯Cu distance of 2.6762 (4) Å. 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—H⋯O hydrogen bonds resulting in one-dimensional chains extending along the crystallographic b axis.
