Abstract: In the title compound, [Cu(C₂H₃O₂)₂(C₅H₈N₂)₂], the Cu^II atom has a distorted tetragonal-bipyramidal geometry, with the equatorial plane formed by two N atoms belonging to two 3,5-dimethyl-1H-pyrazole ligands and two O atoms from two acetate anions. The second O atoms of the acetate groups provide elongated Cu-O axial contacts, so that the acetates appear to be coordinated in a pseudo-chelate fashion. The pyrazole ligands are situated in cis positions with respect to each other. In the crystal structure, molecules are linked through intermolecular N-HO hydrogen bonds, forming a one-dimensional chain.
