| Abstract |
The title Cu(II) complex, [CuBr(2)(C(21)H(15)N(3))]center dot 0.5H(2)O, 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 Cu(II) cation is ligated by three N atoms of L and two bromide anions, forming an irregular CuN(3)Br(2) polyhedron with a distorted square-pyramidal coordination geometry. In the crystal structure, O-H center dot center dot center dot Br hydrogen bonds link the molecules in a three-dimensional network. |
