catena-Poly[di-[mu]3-bromido-hexa-[mu]2-bromido-dibromidobis(O-methyl pyridine-2-carboximidate-[kappa]2N,N')pentamercury(II)]

S. A. Shirvan and M. Hossaini Sadr

Abstract: The title compound, [Hg5Br10(C7H8N2O)2]n, contains two [mu]3-bridging Br atoms, six [mu]2-bridging Br atoms and two terminal Br atoms. One HgII atom, lying on an inversion center, adopts a distorted octahedral geometry defined by six Br atoms. Two HgII atoms adopt a distorted square-pyramidal geometry by five Br atoms and the other two HgII atoms have a distorted tetrahedral geometry by two N atoms from a chelating O-methyl pyridine-2-carboximidate ligand and two Br atoms. The Br atoms link the HgII atoms into a ribbon structure along [100].
