Catena-Poly[[[dichlorido(pyridin-1-ium-3-yl)arsenic(III)]-?-chlorido] mono-hydrate].

ABSTRACT: The crystal structure of the title compound, {[AsCl3(C5H5N)]·H2O} n , is characterized by polymeric chains consisting of alternating arsenic and chlorine atoms running parallel to the a axis. O-H?Cl and N-H?O hydrogen bonds mediated by non-coordinating water mol-ecules assemble these chains into a three-dimensional framework. The As(III) atom, the atoms of the pyridinium ring and the water O atom have m site symmetry and the bridging Cl atom has site symmetry 2. This is the first reported organotrichloro-arsenate(III) in which arsenic adopts a ?-octa-hedral fivefold coordination.

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.

catena-Poly[4-methyl-morpholin-4-ium [[dichloridobismuth(III)]-di-?-chlorido]].

Project description:The asymmetric unit of the title complex, {(C(5)H(12)NO)[BiCl(4)]}(n), contains two bridging and two cis non-bridging chloride ligands coordinated to a central Bi(III) atom, and one 4-methyl-morpholin-4-ium cation. The Bi(III) atoms are linked by the bridging chloride ligands into linear chains parallel to the c axis. The chloride ions create a pseudo-octa-hedral geometry about each Bi(III) atom. Bifurcated N-H?Cl hydrogen bonds link the cations to the anionic chains.

catena-Poly[1-butyl-3-methyl-imidazolium [[dichlorido(methanol-?O)(propan-2-ol-?O)lanthanate(III)]-di-?-chlorido]].

Project description:The title compound, (C(8)H(15)N(2))[LaCl(4)(CH(3)OH)(C(3)H(7)OH)], consists of one 1-butyl-3-methyl-imidazolium (BMI(+)) cation and one hexa-hedral tetra-chlorido(methanol)(propan-2-ol)lanthanate anion. The La(III) ion is eight-coordinate, with the La(III) ion bridged by a pair of Cl atoms, so forming chains propagating along the a-axis direction. Each La(III) ion is further coordinated by two isolated Cl atoms, one methanol and one propan-2-ol mol-ecule. The coordinated methanol and propan-2-ol mol-ecules of the anion form O-H?Cl hydrogen bonds with the Cl atoms of inversion-related anions. The BMI(+) cation froms C-H?Cl hydrogen bonds with the Cl atoms of the anion. The anions are located in the C faces of the triclinic unit cell, with an inversion center in the middle of the La(2)Cl(2) ring of the polymeric chain.

Bis(5-amino-4-amino-carbonyl-1H-imid-azol-3-ium) (5-amino-4-amino-carbonyl-1H-imidazol-3-ium-κO)-di-μ-chlorido-hepta-chlorido-dibismuth(III) mono-hydrate.

Project description:The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-) dianion and a water mol-ecule. In the dianion, the planar 5-amino-4-amino-carbonyl-1H-imidazol-3-ium ligand occupies an equatorial site and is inclined at an angle of 75.7 (2)° to the Bi(2)(μ-C1)(2) plane. The salt forms a three-dimensional network arising from hydrogen bonds between cations, anions and water mol-ecules.

catena-Poly[[[diaqua-cadmium]-?-2,2'-(1,2-phenyl-enedi-oxy)diacetato] mono-hydrate].

Project description:In the title coordination complex, {[Cd(C(10)H(8)O(6))(H(2)O)(2)]·H(2)O}(n) the Cd(II) atom is seven-coordinated in a distorted penta-gonal-bipyramidal geometry, the penta-gonal plane comprising four O-atom donors from the 2,2'-(1,2-phenyl-enedi-oxy)diacetate chelate ligand together with a bridging carboxyl-ate O-atom donor, with the axial sites occupied by two water mol-ecules. The resulting helical chains extend along the b axis and are inter-connected by extensive O-H?O hydrogen-bonding inter-actions, which also involve the water mol-ecule of solvation, giving a three-dimensional structure.

catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].

Project description:The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.

catena-Poly[[penta-?-benzoato-?-chlorido-dioxanedineodymium(III)] dioxane 2.5-solvate].

Project description:The asymmetric unit of the title compound, [Nd(2)(C(6)H(5)COO)(5)Cl(C(4)H(8)O(2))]·2.5C(4)H(8)O(2), consists of two Nd(III) ions bridged by one Cl(-) ion, five benzoate ions and one coordinating 1,4-dioxane mol-ecule. One Nd(III) ion is nine-coordinate, with a very distorted monocapped square-anti-prismatic geometry. It is coordinated by two chelating carboxyl-ate groups, three monodentate carboxyl-ate groups, one chloride ion and one dioxane mol-ecule. A second independent Nd(III) ion is eight-coordinated in a distorted square-anti-prismatic geometry by one chelating carboxyl-ate group, five monodentate carboxyl-ate groups and one chloride ion. The chains of the extended structure are parallel to the crystallographic b axis. There is a small amount of void space which is filled with five disordered dioxane solvent mol-ecules per unit cell. The intensity contribution of the disordered solvent molecules was removed by applying the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148-155].

catena-Poly[[triaqua-chlorido-μ(3)-malonato-cerium(III)] hemihydrate].

Project description:The asymmetric unit of the title compound, {[Ce(C(3)H(2)O(4))Cl(H(2)O)(3)]·0.5H(2)O}(n), contains a Ce(3+) atom coordinated by a chloride anion, three water mol-ecules and a malonate ligand, and one water mol-ecule of crystallization with a factor of occupancy of 50%. The malonate ligand is bonded to three different symmetry-related metal atoms yielding a one-dimensional coordination polymer running parallel to the a axis. A supra-molecular network composed of strong and highly directional O-H⋯O and O-H⋯Cl hydrogen bonds ensures a close and effective packing of adjacent polymeric chains.

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

Project description:In the title coordination polymer, [Hg?Cl?(C??H??N?)](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-HgCl?N? 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?? inter-actions.
