Bis(2,2'-bipyridyl)bromidocopper(II) bromide bromoacetic acid hemihydrate

Y. Liu, J. Sun and X. Wang

Abstract: In the title compound, [CuBr(C₁₀H₈N₂)₂]Br·BrCH₂COOH·0.5H₂O, the Cu^II ion is coordinated by four N atoms [Cu-N = 1.985 (6)-2.125 (7) Å] from two 2,2'-bipyridine ligand molecules and a bromide anion [Cu-Br = 2.471 (2) Å] in a distorted trigonal-bipyramidal geometry. Short centroid-centroid distances [3.762 (5) and 3.867 (5) Å] between the aromatic rings of neighbouring cations suggest the existence of - interactions. Intermolecular O-HBr hydrogen bonds and weak C-HO and C-HBr interactions consolidate the crystal packing.
