Bis(2,1,3-benzoselenadiazole-κN)dibromidocopper(II)

Abstract

In the title complex, [CuBr2(C6H4N2Se)2], the CuII ion is tetracoordinated by two bromide anions and two N atoms in a distorted square-planar geometry. The two essentially planar 2,1,3-benzoselenadiazole ligands [maximum deviations = 0.012 (2) and 0.030 (2) Å] are approximately coplanar [dihedral angle = 6.14 (6)°]. In the crystal, short intermolecular Se...Br, Se...N and N...N interactions are observed. These short interactions and intermolecular C—H...Br hydrogen bonds link the complex molecules into two-dimensional arrays parallel to the ac plane.
