Dibromido(4′-phenyl-2,2′:6′,2′′-terpyridyl)copper(II) hemihydrate

Abstract

The title CuII complex, [CuBr2(C21H15N3)]·0.5H2O, was obtained by the hydro­thermal reaction of copper(II) bromide, 4′-phenyl-2,2′:6′,2′′-terpyridyl (4′-Ph-terpy or L) and sodium citrate in water in 31% yield. There are two unique complex mol­ecules and a water mol­ecule in the asymmetric unit. The CuII cation is ligated by three N atoms of L and two bromide anions, forming an irregular CuN3Br2 polyhedron with a distorted square-pyramidal coordination geometry. In the crystal structure, O—H⋯Br hydrogen bonds link the mol­ecules in a three-dimensional network.
