Abstract
The title compound is a co-crystal of the cis and trans isomers, namely cis-bis[1,1,1,5,5,5-hexafluoropentane-2,4-dionato(1−)-κ2 O,O′]bis(4-phenylpyridine N-oxide-κO)copper(II)–trans-bis[1,1,1,5,5,5-hexafluoropentane-2,4-dionato(1−)-κ2 O,O′]bis(4-phenylpyridine N-oxide-κO)copper(II) (2/1), [Cu(C5HF6O2)2(C11H9NO)2]. In both isomers, the coordination geometry of the Cu2+ atom is octahedral, exhibiting typical Jahn–Teller distortion. The metal atom of the trans isomer is located on an inversion centre. In the cis isomer, the phenyl ring in one 4-phenylpyridine N-oxide ligand is disordered over two orientations in a 1:1 ratio. In the crystal, weak intermolecular C—H⋯F and C—H⋯O contacts establish connections between the cis and trans isomers.
