Abstract
In the title centrosymmetric mononuclear copper(II) complex, [Cu(C8H7BrNO2)2], the CuII atom, lying on an inversion centre, is four-coordinated in a trans-CuN2O2 square-planar geometry by two phenolate O atoms and two oxime N atoms from two symmetry-related N,O-bidentate oxime-type ligands. Intermolecular C—H⋯O hydrogen bonds link neighbouring molecules into a one-dimensional supramolecular structure with an R 2 2(14) ring motif. This structure is further stabilized by π–π stacking interactions between adjacent benzene rings [centroid–centroid distance = 3.862 (1) Å].
