Di-?-bromido-bis-[bromido(4,4'-dimethyl-2,2'-bipyridine-?N,N')mercury(II)].

ABSTRACT: The asymmetric unit of the title compound, [Hg(2)Br(4)(C(12)H(12)N(2))(2)], contains one half-mol-ecule. The Hg(II) atom is five-coordinated in a trigonal-bipyramidal configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, two bridging Br and one terminal Br atom, leading to a centrosymmetric dimeric mol-ecule. There is a ?-? contact between the pyridine rings [centroid-to-centroid distance = 3.756?(5)?Å].

Project description:In the crystal of the title polymeric compound, [CdBr2(C12H12N2)] n , the Cd(II) cation is located on a twofold rotation axis and is six-coordinated in a distorted octa-hedral geometry formed by two N atoms from the 4,4'-dimethyl-2,2'-bipyridine ligand and by four bridging Br(-) anions. The bridging function of the Br(-) anions leads to a polymeric chain running along the c axis. Weak C-H?? inter-actions observed between adjacent chains are effective in the stabilization of the three-dimensional packing.
