Catena-Poly[[bis-(pyrazine-2-carbox-amide)mercury(II)]-di-?-chlorido].

ABSTRACT: 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.

Project description:In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(-) anions in a distorted octa-hedral geometry. The Br(-) anions bridge the Hg(II) cations with significantly different Hg-Br bond distances of 2.4775 (8) and 3.1122 (8) Å, forming polymeric chains running along the a axis. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds are effective in the stabilization of the crystal structure.

Isotypic one-dimensional coordination polymers: catena-poly[[di-chlorido-cadmium]-μ-5,6-bis-(pyridin-2-yl)pyrazine-2,3-di-carboxyl-ato-κ(2) N (5):N (6)] and catena-poly[[di-chlorido-mercury(II)]-μ-5,6-bis-(pyridin-2-yl)pyrazine-2,3-di-carboxyl-ato-κ(2) N (5):N (6)].

Project description:The isotypic title one-dimensional coordination polymers, [CdCl2(C18H14N4O4)] n , (I), and [HgCl2(C18H14N4O4)] n , (II), are, respectively, the cadmium(II) and mercury(II) complexes of the dimethyl ester of 5,6-bis-(pyridin-2-yl)pyrazine-2,3-di-carb-oxy-lic acid. In both compounds, the metal ions are located on a twofold rotation axis and a second such axis bis-ects the Car-Car bonds of the pyrazine ring. The metal ions are bridged by binding to the N atoms of the two pyridine rings and have an MN2Cl2 bisphenoidal coordination geometry. The metal-Npyrazine distances are much longer than the metal-Npyridine distances; the difference is 0.389 (2) Å for the Cd-N bonds but only 0.286 (5) Å for the Hg-N bond lengths. In the crystals of both compounds, the polymer chains are linked via pairs of C-H⋯Cl hydrogen bonds, forming corrugated slabs parallel to the ac plane.

catena-Poly[[chloridomercury(II)]-μ-1,4-diaza-bicyclo-[2.2.2]octane-κN:N'-[chlorido-mercury(II)]-di-μ-chlorido].

Project description:In the title coordination polymer, [Hg(2)Cl(4)(C(6)H(12)N(2))](n), each Hg(II) center within the chain is four-coordinated by one terminal Cl atom, two bridging μ(2)-Cl atoms, and one N-atom donor from a μ(2)-1,4-diaza-bicyclo-[2.2.2]octane (μ(2)-daco) ligand in a distorted tetra-hedral geometry. The daco ligand acts as an end-to-end bridging ligand and bridges adjacent Hg(II) centers, forming a chain running along [001]. Weak C-H⋯Cl hydrogen-bonding inter-actions link the chains into a three-dimensional network. Comparison of the structural differences with previous findings suggests that the space between the two N donors, as well as the skeletal rigidity in N-heterocyclic linear ligands, may play an important role in the construction of such supra-molecular networks.

catena-Poly[bis(1,3-benzo-thia-zol-3-ium) [[di-chlorido-anti-monate(III)]-di-μ-chlorido-μ-oxido-[chlorido-anti-monate(III)]-μ-chlorido]].

Project description:The title compound, {(C7H6NS)2[Sb2Cl6O]} n , contains two benzo-thia-zolidium cations and one tri-μ-chlorido-tri-chlorido-μ-oxido-di-anti-monate(III) anion. The structure of the inorganic cation may be described as as being built up from two polyhedra, i.e. a square-pyramidal SbCl4O and a distorted octa-hedral SbOCl5 unit, sharing a common face (comprising the O atom and two Cl atoms). The two benzo-thia-zole cations are quasi-planar and subtend a dihedral angle of 19.93 (5)°. The crystal packing can be described by alternating (100) layers and [001] chains of the organic cations and inorganic anions connected through an extensive three-dimensional network of N-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds. This is consolidated by slipped π-π stacking, with centroid-to-centroid distances between the benzo-thia-zole rings of 3.7111 (18)-3.8452 (16) Å. These inter-actions link the mol-ecules within the layers and also link the layers together and reinforce the cohesion of the ionic structure.

Project description: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.

catena-Poly[(dichloridocadmium)-di-?-chlorido-[bis-(morpholinium-?O)cadmium]-di-?-chlorido].

Project description:In the title compound, [Cd(2)Cl(6)(C(4)H(10)NO)(2)](n), the coordination geometry of each Cd(II) ion is distorted octa-hedral, but with quite different coordination environments. One Cd(II) atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating a chain parallel to the a axis. Inter-chain N-H?Cl inter-actions form a two-dimensional network.

catena-Poly[[(benzil bis{[(pyridin-2-yl)methylidene]hydrazone}-κ⁴N,N',N'',N''')mercury(II)]-μ-chlorido-[dichloridomercury(II)]-μ-chlorido].

Project description:In the title coordination polymer, [Hg₄Cl₄(C₂₆H₂₀N₆)](n), one Hg(II) ion is coordinated by four N atoms from the benzylbis((pyridin-2-yl)methyl-idenehydrazone) ligand and two Cl⁻ ions in a very distorted cis-HgCl₂N₄ octa-hedral geometry. The other Hg(II) ion is coordinated in a distorted tetra-hedral geometry by four Cl⁻ ions. Bridging chloride ions link the Hg(II) ions into a chain propagating in [010]: the Hg-Cl bridging bonds are significantly longer than the terminal bonds. The dihedral angle between the central benzene rings of the ligand is 83.3 (2)°. The packing is consolidated by weak C-H⋯Cl hydrogen bonds and C-H⋯π inter-actions.

catena-Poly[bis-(sulfamethoxazolium) [[trichloridocadmate(II)]-μ-chlorido] monohydrate].

Project description:In the title compound, {(C(10)H(12)N(3)O(3)S)(2)[CdCl(4)]·H(2)O}(n), the Cd(II) atom is five-coordinate with a distorted trigonal-bipyramidal geometry formed by chloride ions. The Cd atom and two of the Cl atoms lie on a mirror plane. The cation is protonated on the amino group N atom; it is not coordinated to cadmium, but is hydrogen bonded to the chlorido ligands. Each water mol-ecule bridges two chlorido ligands, generating ring motifs along the -Cd-Cl-Cd- chains. The isoxazole unit and the amide groups are linked through a pair of N-H⋯N hydrogen bonds. The crystal structure is stabilized by N-H⋯O, O-H⋯Cl, C-H⋯N, N-H⋯Cl and C-H⋯O hydrogen bonds.

catena-Poly[[chloridocopper(II)]bis-(μ-3,3',5,5'-tetra-methyl-4,4'-methylene-dipyrazole)[chloridocopper(II)]-di-μ-chlorido].

Project description:In the title compound, [Cu(2)Cl(4)(C(11)H(16)N(4))](n), the Cu atom is coordinated by two N atoms of two 3,3',5,5'-tetra-methyl-4,4'-methyl-enedipyrazole (H(2)mbdpz) ligands, two bridging Cl atoms and one terminal Cl atom, forming a square-pyramidal geometry. The bridging Cl atoms and the bridging H(2)mbdpz ligands connect the Cu atoms to build up an extended one-dimensional chain. The chains are further connected through N-H⋯Cl hydrogen bonds to build up a two-dimensional layer in the (011) plane. An inversion centre lies between every pair of adjacent Cu atoms.

catena-Poly[[di-μ-chlorido-dicopper(I)]bis-[μ-η,σ-4-(2-allyl-2H-tetra-zol-5-yl)pyridine]].

Project description:The title polymer, [Cu(2)Cl(2)(C(9)H(9)N(5))(2)](n), has been prepared by the solvothermal treatment of CuCl with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine. The crystal structure shows that the title compound is a homometallic Cu(I)-olefin coordination polymer, in which the Cu(2)Cl(2) nodes are bridged by two olefin ligands. The asymmetric unit contains one-half of the monomer, the complete monomer having twofold rotation symmetry. The coordination environment of Cu(I) is slightly distorted tetra-hedral, with coordination sites being two μ(2)-Cl atoms, one pyridine N atom of an organic ligand and one allylic double bond of a symmetry-related ligand. Each organic mol-ecule behaves as a bidentate ligand, connecting two neighboring Cu(2)Cl(2) dimers in the polymeric chain, which runs along [010].
