Bis(2,2'-bipyridine-?N,N')dibromido-cadmium(II).

Project description:In the title complex mol-ecule, [CdBr(2)(C(10)H(8)N(2))(2)], the Cd(II) ion is six-coordinated by two cis-arranged bromide anions and four N atoms of two bidentate 2,2'-bipyridine ligands in a distorted octa-hedral geometry.

The chains are further connected by inter-molecular C-H?Br hydrogen bonds into a three-dimensional network.
