The title compound Cu2(μ-Cl)2Cl2(3,5-diphenyl-1H-pyrazole)2(DMF)2, where DMF is N,N-dimethylformamide, consists of two five-coordinate CuII ions with a distorted square-pyramidal geometry connected via two μ-Cl anions. The coordination environment of each CuII ion is completed by a terminal chloride anion, a nitrogen-coordinated 3,5-diphenyl-1H-pyrazole molecule, and a DMF molecule. Intermolecular hydrogen bonding between the molecules generates a two-dimensional sheet.
