Catena-Poly[N,N,N',N'-tetra-methyl-ethylendi-ammonium [[tetra-bromido-antimonate(III)]-μ-bromido] hemihydrate].

ABSTRACT: The asymmetric unit of the title compound {(C6H18N2)2[Sb2Br10]·H2O} n , consists of two tetra-methyl-ethylendi-ammonium cations that are located on centres of inversion, as well as one tetra-methyl-ethylendi-ammonium cation, one water mol-ecule, one distorted octahedral [SbBr6](3-)anion and one bisphenoidal [SbBr4](-) anion in general positions. The [SbBr6](3-) and [SbBr4](-) anions are linked together by two long Sb-Br bonds of 3.2709 (8) and 3.5447 (7) Å into {[Sb2Br10](4-)} n chains along [001]. One of the three tetra-methyl-ethylendi-ammonium cations is disordered and was refined using a split model (occupancy ratio 0.58:0.42). The cations and the water mol-ecule are connected to the {[Sb2Br10](4-)} n polymeric anions by weak N-H ⋯Br and O(water)-H ⋯Br hydrogen bonding.

catena-Poly[heptyl-enedi-ammonium [[tetra-chloridobismuthate(III)]-μ-chlorido]].

Project description:The title organic-inorganic hybrid compound, {(C7H20N2)[BiCl5]} n , consists of distorted corner-joined [BiCl6] octa-hedra forming zigzag polymeric anionic chains parallel to [001], separated by columns of heptyl-enedi-ammonium cations. The asymmetric unit contains two crystallographically independent bis-muth metal atoms, one of which lies on an inversion centre and the other on a twofold axis. In the crystal, the polymeric chains and cations are linked by N-H⋯Cl hydrogen bonds, forming undulating layers parallel to (110).

catena-Poly[trimethyl-phenyl-ammonium [[bromidocad-mate(II)]-μ-bromido-μ-chlorido]].

Project description:In the title salt, (C(9)H(14)N)[CdBr(2)Cl], the Cd(II) atom is five-coordinated in a trigonal-bipyramidal coordination environment. All three of the halogen sites show disorder as a result of substitution of Cl for Br or Br for Cl. Two of the three halogen atoms are involved in bridging a pair of Cd(II) atoms, generating a linear polyanionic chain motif.

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.

Tetra-methyl-ammonium dihydrogen phosphate hemihydrate.

Project description:In the crystal structure of the title compound, C(4)H(12)N(+)·H(2)PO(4) (-)·0.5H(2)O, the anions form an infinite hydrogen-bonded chain along the [10] direction. The anion chains are connected by water mol-ecules, which lie on crystallographic twofold rotation axes, through O-H?O hydrogen bonds. These hydrogen bonds are almost perpendicular to the other hydrogen bonds which create an assembled structure of anions. In addition, C-H?O hydrogen bonds between anions and cations are observed.

catena-Poly[[[tetra-aqua-magnesium]-trans-μ-[(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nato] hemihydrate].

Project description:The structure of the title polymer, }[Mg(C6H14N2O6P2)(H2O)4]·0.5H2O} n , is based on centrosymmetric MgO6 octahedra, which are linked by [(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nate ligands, forming chains parallel to [1-1-1]. These chains are connected via hydrogen bonds primarily formed between the phospho-nate groups and water mol-ecules. The latter constitute four of the corners of the MgO6 polyhedra and bind to the O atoms of the phospho-nate groups of neighbouring chains. The lattice water molecule is disordered around an inversion centre, exhibiting an occupancy of 0.25.

Poly[bis(phenethyl-ammonium) [di-bromido-plumbate(II)]-di-μ-bromido]].

Project description:Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(n), were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr(6) octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra are rotated and tilted due to N-H⋯Br hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetra-chloridoplumbate (C(6)H(5)C(2)H(4)NH(3))(2)[PbCl(4)].

catena-Poly[[(tetra-hydro-furan-κO)lithium(I)]-bis-(μ-trimethyl-silanolato-κO:O)-gallium(III)-bis-(μ-trimethyl-silanolato-κO:O)-[(tetra-hydro-furan-κO)lithium(I)]-μ-bromido].

Project description:The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion centre, two trimethyl-silanolate ligands and one tetra-hydro-furane mol-ecule in a distorted tetra-hedral geometry. The polymeric chains extend along [001]. The tetra-hydro-furane mol-ecule is disordered over two positions with site-occupancy factors of 0.57 (2) and 0.43 (2).

catena-Poly[[[tetra-aqua-samarium(III)]-di-μ-isonicotinato-κO:O'] chloride].

Project description:In the structure of the title compound, {[Sm(C(6)H(4)NO(2))(2)(H(2)O)(4)]Cl}(n), the unique Sm(III) atom lies on a crystallographic twofold axis and is eight-coordinated by four O atoms from four isonicotinate ligands and four water mol-ecules in a slightly distorted square-anti-prismatic coodination environment. The Sm(III) atoms are bridged by two carboxyl-ate groups of two isonicotinate ligands, forming an extended chain along the c-axis direction. These chains are cross-linked through hydrogen bonds, forming a three-dimensional framework, with channels which accommodate the chloride anions.

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

Project description:The title compound, [CuBr(C(9)H(9)N(5))](n), prepared by the solvothermal treatment of CuBr with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, is a new homometallic Cu(I)-olefin coordination polymer in which dinuclear Cu(2)Br(2) units are linked by the organic olefin ligand 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, which acts as a bidentate ligand connecting two neighbouring Cu(2)Br(2) units through the pyridine N atom and the double bond of the allyl group. The coordination of Cu(I) is slightly distorted tetrahedral.

Poly[tetra-aqua-μ(3)-benzene-1,2-di-carboxyl-ato-μ(3)-bromido-penta-μ(2)-bromido-octa-μ(3)-isonicotinato-hepta-copper(I)trilanthanum(III)].

Project description:A new lanthanum(III)-copper(I) heterometallic coordination polymer, [Cu(7)La(3)Br(6)(C(6)H(4)NO(2))(8)(C(8)H(4)O(4))(H(2)O)(4)](n), has been prepared by a hydro-thermal method. Of the three La atoms in the asymmetric unit, two are eight-coordinate with bicapped trigonal-prismatic configurations; the third is nine-coordinated and has a tricapped trigonal-prismatic coordination geometry. Of the seven Cu atoms, two are two-coordinate with CuBrN and CuN(2) ligand sets, three have trigonal configurations, viz. CuBrN(2), CuBr(2)N and CuBr(3), while the remaining two adopt distorted tetra-hedral CuBr(3)N geometries. In the crystal structure, adjacent La centers are linked by isonicotinate (IN(-)) and benzene-1,2-dicarboxyl-ate ligands to form a two-dimensional La-carboxyl-ate layer in the ab plane. These layers are further inter-connected with each other by bridging [Cu(IN)(2)] motifs, leading to an unusual three-dimensional heterometallic Cu-halide-lanthanide-organic framework, with the inorganic [Cu(6)Br(6)](n) chains located in the resulting channels. Two Cu atoms are disordered over two positions, both with site occupancy factors of 0.80 and 0.20. O-H⋯O hydrogen bonding between water molecules and carboxylate O atoms helps to consolidate the crystal packing.
