Poly[[penta-aqua-bis-(?3-hydrogen squarato)barium] monohydrate].

ABSTRACT: The crystal structure of the title compound, {[Ba(C4HO4)2(H2O)5]·H2O} n , consists of discrete double chains propagating along [010]. The chains are formed by Ba(II) ions linked by bridging hydrogen squarate ligands in a trans-bis-monodentate mode. In addition, the bridging hydrogen squarate ligands connect the chains into a ladder structure via a third coordinating O atom. The remaining coordination sites are occupied by five aqua ligands and a second mondendate hydrogen squarate ligand, forming a slightly distorted tricapped trigonal-prismatic geometry. O-H?O hydrogen bonds link the chains and solvent water mol-ecules into a three-dimensional network.

Poly[tetra-aqua-bis(?(2)-2,4,6-trinitro-phenolato)barium(II)].

Project description:The asymmetric unit of the title compound, [Ba(C(6)H(2)N(3)O(7))(2)(H(2)O)(4)](n), consists of a barium ion coordinated by two nitrophenolate ligands and four water mol-ecules. Barium is deca-coordinated by O atoms. These units are linked together through bridging nitro groups to form a one-dimensional polymeric chain. The three-dimensional packing is facilitated through hydrogen-bonding inter-actions mediated through water mol-ecules. The coordination distances around Ba vary from 2.728?(4) to 3.138?(5)?Å. The crystal sample, on exposure to air at room temperature for many days, slowly loses the water and peels out as filaments.

Poly[[?(2)-aqua-aqua-(?(3)-3,5-dinitro-salicylato)barium(II)] monohydrate].

Project description:In the title coordination polymer, {[Ba(C(7)H(2)N(2)O(7))(H(2)O)(2)]·H(2)O}(n), the Ba(II) atom is ten-coordinated by seven O atoms from four 3,5-dinitro-salicylatate ligands, two ?(2)-bridging aqua ligands and one water mol-ecule. The coordination mode is best described as a bicapped square-anti-prismatic geometry. The 3,5-dinitrosalicylatate ligands bridge three Ba atoms. Centrosymmetrically related dinuclear barium units, with a Ba?Ba separation of 4.767?(5)?Å, form infinite chains, which are further self-assembled into a supra-molecular network through inter-molecular O-H?O hydrogen-bonding inter-actions between O atoms of 3,5-dinitro-salicylatate ligands and water mol-ecules.

Monoclinic polymorph of poly[[di-μ-aqua-triaquadi-μ-oxalato-barium(II)-copper(II)] monohydrate].

Project description:A monoclinic polymorph of the title compound, {[BaCu(C(2)O(4))(2)(H(2)O)(5)]·H(2)O}(n), is reported. The structure is best described as a coordination polymer where the Cu(II) and Ba(II) centers are coordinated by five and nine O atoms, respectively, in capped quadratic antiprismatic and tetragonal pyramidal geometries. The polymerization arises due to the presence of bridging mono- and bidentate oxalate ligands as well as bridging water mol-ecules. The crystal structure is consolidated by a three-dimensional network of hydrogen bonding.

Poly[[tetra-aqua-bis(1H-imidazole-κN)bis-[2-(oxaloamino)benzoato(3-)]dicopper(II)barium(II)] dihydrate].

Project description:In the title coordination polymer, {[BaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(4)]·2H(2)O}(n), the Ba(2+) cation is deca-coordinate, ligated by four aqua ligands and four [Cu(C(9)H(4)O(5)N)(C(3)H(4)N(2))] 'complex ligands'. The Cu(II)-containing complex-ligands are bridged by the Ba(2+) cations, resulting in a one-dimensional polymeric chain structure. The crystal structure is maintained via N-H⋯O and O-H⋯O hydrogen bonds. There is one disordered solvent water mol-ecule in the asymmetric unit, with occupancies of 0.44 (2) and 0.56 (2).

Poly[(?(5)-5-amino-isophthalato)aqua-barium].

Project description:In the title compound, [Ba(C(8)H(5)NO(4))(H(2)O)](n), the Ba(II) ion is eight-coordinated by six O atoms and one N atom from five 5-amino-isophthalate ligands and one water mol-ecule in a distorted dodeca-hedral geometry. The Ba(II) ions are connected via the ligands into a layer parallel to (011). The layers are linked by N-H?O hydrogen bonds. The coordinated water mol-ecule is involved in intra-layer O-H?O hydrogen bonds.

catena-Poly[[[aqua-(pyrazino-[2,3-f][1,10]phenanthroline-?N,N)zinc(II)]-?-penta-nedioato] monohydrate].

Project description:In the title compound, {[Zn(C(5)H(6)O(4))(C(14)H(8)N(4))(H(2)O)]·H(2)O}(n), the Zn(2+) ion is coordinated by an N,N'-bidentate pyrazino-[2,3-f][1,10]phenanthroline (pyphen) ligand, a water molecule and a monodentate glutarate (glu) dianion. A symmetry-generated O:O'-bidentate glu dianion completes a distorted cis-ZnN(2)O(4) octa-hedral coordination geometry for the metal ion. The bridging glu species generates [110] polymeric chains in the crystal. O-H?O hydrogen bonds involving both the coordinated and uncoordinated water mol-ecules help to consolidate the structure and neighbouring pyphen units inter-act through numerous aromatic ?-? inter-actions [minimum centroid-centroid separation = 3.654?(3)?Å], resulting in a two-dimensional network.

catena-Poly[[?(2)-aqua-diaqua-bis-(?(4)-pyridazine-3,6-dicarboxyl-ato)tetra-lithium] monohydrate].

Project description:In the polymeric structure of the title compound {[Li(2)(C(6)H(2)N(2)O(4))(2)Li(H(2)O)(2)Li(H(2)O)]·H(2)O}(n), the coordination of two independent Li(I) ions is distorted trigonal-bipyramidal and that of the other two independent Li(I) ions is distorted tetra-hedral. The former two Li(I) ions are bridged by hetero-ring N atoms of two independent pyridazine-3,6-dicarboxyl-ate ligands, making a dimeric moiety. The carboxyl-ato-O atoms of both bidentate ligands bridge the dimers to adjacent independent aqua-coordinated Li(I) ions, forming mol-ecular ribbons. The latter are bridged by ligand carboxyl-ato and aqua O atoms, forming mol-ecular layers parallel to (100) which are held together by an extended system of O-H?O hydrogen bonds.

Bis(cytosinium) aqua-penta-chlorido-indate(III).

Project description:The asymmetric unit of the title compound, (C(4)H(6)N(3)O)(2)[InCl(5)(H(2)O)], comprises two independent cytosinium cations and an aquapentachloridoindate anion. The In(III) ion is in a slightly distorted octa-hedral coordination geometry. In the crystal, alternating layers of cations and anions are arranged along [010] and are linked via inter-molecular N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, forming sheets parallel to (001). Additional stabilization within these sheeets is provided by weak inter-molecular C-H⋯O inter-actions.

Poly[μ-aqua-aqua-μ4-naphthalene-1,8-dicarboxyl-ato-barium]: a layer structure.

Project description:The title compound, [Ba(C12H6O4)(H2O)2] n , is represented by a layer-like structure built of BaO8 polyhedra. The asymmetric unit contains a Ba(2+) ion, half a coordinating water mol-ecule and half a μ4-bridging naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligand, the whole structure being generated by twofold rotational symmetry. The carboxyl-ate groups of the 1,8-nap ligands act as bridges linking four Ba(2+) ions, while each Ba(2+) ion is eight-coordinated by O atoms from four 1,8-nap ligands and two coordinating water mol-ecules. In the crystal, there are O-H⋯O hydrogen bonds involving the water mol-ecules and carboxyl-ate O atoms in the BaO8 polyhedra. Each BaO8 polyhedron is connected via corner-sharing water O atoms or edge-sharing ligand O atoms, forming a sheet parallel to the bc plane. These sheets stack along the a-axis direction and are connected via van der Waals forces only. The naphthalene groups protrude above and below the layers of the BaO8 polyhedra and there are voids of ca 208 Å(3) bounded by these groups. No residual electron density was found in this region. The crystal studied was twinned by pseudo-merohedry, with a refined twin component ratio of 0.5261 (1):0.4739 (1).

Aqua-bis-(4-methyl-benzene-sulfonato-?O)(?(5)-penta-methyl-cyclo-penta-dien-yl)rhodium(III) monohydrate.

Project description:The title half-sandwich rhodium(III) complex, [Rh(C10H15)(C7H7O3S)2(H2O)]·H2O, consists of a ?-bonded penta-methyl-cyclo-penta-dienyl group, two ?-bonded tosyl-ate groups and an aqua ligand. The structure displays both inter- and intra-molecular O-H?O hydrogen bonding. The inter-molecular hydrogen bonding results in an extended helical chain along a 21 screw axis parallel to c, due to hydrogen bonding from the coordinating water ligand to the lattice water mol-ecule and then to a sulfonate O atom of a different asymmetric unit.
