چکیده
In the title organometallic polymer, [HgCl(2)(C(26)H(20)NO(3)P)](n), the monodentate 1-(3-nitro-phen-yl)-2-(triphenyl-phospho-ran-yl--idene)ethanone ligand is coordinated to the Hg(II) atom through the methine C atom. The Hg(II) atom is four-coordinated in a distorted tetra-hedral geometry by one terminal Cl atom, two bridging Cl atoms, and one C atom from the ylidic ligand, resulting in a polymeric chain parallel to [010]. The terminal Cl atom is more strongly bound to the Hg(II) ion [2.3916 (9) Å] than the bridging Cl atoms. The bridge is asymmetric, as indicated by the two different Hg-Cl(bridging) bond lengths [2.5840 (8) and 2.7876 (8) Å]. Intra-molecular C-H⋯O and weak C-H⋯Cl contacts stabilize the polymeric chain. In the crystal, adjacent chains inter-act via C-H⋯O hydrogen bonds.

The title compound, [HgCl(2)(C(7)H(8)S)](n), was isolated from the reaction of MeSPh with HgCl(2). The Hg(II) atom has a distorted tetra-hedral geometry and is coordinated by one S atom and three Cl atoms. Two of the Cl atoms act as bridging ligands between the Hg atoms, forming a two-dimensional polymeric structure.

In the polymeric title compound, [HgCl(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) atom (site symmetry ) adopts a distorted trans-HgN(2)Cl(4) octa-hedral coordination geometry. In the crystal, adjacent mercury ions are bridged by pairs of chloride ions, generating infinite [100] chains, and N-H⋯O and N-H⋯(N,N) hydrogen bonds help to consolidate the packing.

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

In the title compound, [HgCl(2)(C(6)H(5)NO(2))(2)](n), the Hg(II) cation is located on an inversion center and is six-coordinated in a distorted octa-hedral geometry by two N atoms from two pyridine-3-carb-oxy-lic acid mol-ecules and four bridging Cl(-) anions. The bridging function of the Cl(-) anions leads to polymeric chains running along the a axis. One Hg-Cl bond is much longer than the ot...
