Poly[[?(4)-tartrato-cadmium(II)] 0.167-hydrate].

ABSTRACT: The title compound, {[Cd(C(4)H(4)O(6))]·0.167H(2)O}(n), adopts a three-dimensional network structure in which each Cd(II) ion is chelated by two pairs of carboxyl-ate and hydroxyl O atoms from two tartrate anions, and is additionally linked to two O atoms of two carboxyl-ate groups that are not involved in chelation. The asymmetric unit has four independent cadmium atoms, two of which lie on special positions of 2 site symmetry. The tartrate anions all lie on general positions. All hydroxyl groups are engaged in O-H?O hydrogen-bonds, one of which is also bifurcated. The non-coordinating water molecule is situated on a site with half-occupation.

Poly[[diaqua-(μ(4)-l-tartrato)(μ(2)-l-tartrato)dizinc(II)] tetra-hydrate].

Project description:In the title compound, {[Zn(C(4)H(4)O(6))(H(2)O)]·2H(2)O}(n), the l-tartrate ligands adopt μ(4)- and μ(2)-coordination modes. The Zn(II) atom adopts an octa-hedral geometry and is chelated by two kinds of l-tartrate ligands through the hydr-oxy and carboxyl-ate groups and coordinated by one unchelating carboxyl-ate O atom and one water mol-ecule. In the crystal, the l-tartrate ligands link the Zn(II) atoms, forming a two-dimensional coordination layer; these layers are futher linked into a three-dimensional supra-molecular network by O-H⋯O hydrogen bonds between the two-dimensional coordin-ation layers and the uncoordinated water mol-ecules. The latter are equally disordered over two positions.

Poly[[(1,10-phenanthroline)(?-l-tartrato)zinc] hexa-hydrate].

Project description:The title compouand {[Zn(C(4)H(4)O(6))(C(12)H(8)N(2))]·6H(2)O}(n), has a linear chain structure parallel to [100] with Zn(C(4)H(4)O(6))(C(12)H(8)N(2)) repeat units; the asymmetric unit consists of one Zn(2+) cation, one l-tartrate dianion, one 1,10-phenanthroline and six free water mol-ecules. The Zn atom is in a distorted octa-hedral ZnN(2)O(4) coordination environment. The crystal structure is stabilized by O-H?O hydrogen bonds and ?-? stacking of the phenanthroline units [centroid-centroid distances in the range 3.552?(2)-3.625?(2)Å] occurs between the chains. The title compound is isotypic with the Cu and Mn analogues.

Project description:In the title compound, {[Mn(C(4)H(4)O(6))(H(2)O)]·H(2)O}(n), the Mn(2+) ion is connected to three different tartrate anions and a water mol-ecule, resulting in a distorted MnO(6) octa-hedral geometry. There are two tartrate half-anions in the asymmetric unit, both of which are completed by crystallographic twofold rotation symmetry. The tartrate dianions bridge the Mn(2+) ions to form a wave-like infinite layer. A series of O-H⋯O hydrogen bonds link the layers into a three-dimensional network.

Project description:In the crystal structure of the title compound, [Cd(C(10)H(8)N(2))(H(2)O)(4)](C(4)H(2)O(4))·4H(2)O, the Cd(II) atom, on an inversion centre, is six-coordinated by four O atoms from four water mol-ecules and two N atoms from 4,4'-bpy mol-ecules in a distorted octa-hedral coordination geometry. Weak C-H⋯O inter-actions between uncoordinated carboxyl-ate O atoms of fumaric acid and water mol-ecules contribute to the crystal packing stability.

catena-Poly[[[diaqua-cadmium(II)]-bis-[μ-3,5-bis-(isonicotinamido)benzoato]] tetra-hydrate].

Project description:The title compound, {[Cd(C(19)H(13)N(4)O(4))(2)(H(2)O)(2)]·4H(2)O}(n) or {[Cd(BBA)(2)(H(2)O)(2)]·4H(2)O}(n), where BBA is 3,5-bis-(iso-nicotin-amido)-benzoate, is isotypic with its Mn isologue [Chen et al. (2009 ▶). J. Coord. Chem.62, 2421-2428]. The cation sits on a twofold axis and is six-coordinated in a slightly distorted octa-hedral geometry; the polyhedra are linked into zigzag chains, which are further connected by N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds as well as π-π inter-actions [centroid-centroid distance of 3.639 (2) Å], giving a three-dimensional supra-molecular framework.

Poly[[{?(2)-3-[(1H-benzimidazol-1-yl)meth-yl]benzoato}cadmium(II)] 0.1-hydrate].

Project description:In the title polymeric compound, {[Cd(C(15)H(11)N(2)O(2))(2)]·0.1H(2)O}(n), the Cd(II) atom is coordinated by four carboxyl-ate O atoms and two benzimidazole N atoms from four benzimidazolylmethyl-benzoate anions in a distorted octa-hedral geometry. Each anion bridges two Cd atoms through the terminal carboxyl-ate group and an imidazole N atom, forming polymeric complex chains running along the b axis. The uncoordinated water mol-ecule is equally disordered over two sites; occupancies were fixed as 0.5 for each disordered component. Weak inter-molecular C-H?O hydrogen bonding is present in the crystal structure.

catena-Poly[[[aqua-cadmium(II)]bis-(?-4-hydroxy-pyridine-2,6-dicarboxyl-ato)[aqua-cadmium(II)]di-?-aqua] tetra-hydrate].

Project description:The title polymeric compound, {[Cd(2)(C(7)H(3)NO(5))(2)(H(2)O)(4)]·4H(2)O}(n) or {[Cd(2)(hypydc)(2)(H(2)O)(4)]·4H(2)O}(n) (where hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of cadmium(II) nitrate hexa-hydrate with 4-hydroxy-pyridine-2,6-dicarboxylic acid and propane-1,3-diamine, in a 1:2:2 molar ratio in aqueous solution. The compound is a seven-coordinate binuclear polymeric complex with distorted penta-gonal bipyramidal geometry around Cd(II) [Cd-O = 2.247?(4)-2.474?(3)?Å]. In the binuclear monomeric units, the central atoms join together by O atoms of two bridging tridentate (hypydc)(2-) ligands, and the polymer propagates via two bridging water mol-ecules that link each Cd(II )centre of one monomer to the adjacent neighbour. Propane-1,3-diamine (pn) does not appear in the product but plays a role as a base. Inter-molecular O-H?O and C-H?O hydrogen bonds, and ?-? stacking inter-actions, with distances of 3.725?(3) and 3.766?(3)?Å, connect the various components.

Project description:In the title compound, {[CdCl(2)(C(16)H(20)N(4))(2)]·4H(2)O}(n), octa-hedrally coordinated Cd(II) ions, situated on crystallographic inversion centres, bearing trans-disposed chloride ligands, are linked into (4,4)-grid coordination polymer layers by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine ligands. The layers are aligned parallel to the (01) crystal planes and aggregate by means of O-H?N, O-H?O and O-H?Cl hydrogen-bonding mechanisms imparted by cyclic water mol-ecule tetra-mers.

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.

Poly[[triaqua-tri-?(5)-tartrato-dilanthanum(III)] dihydrate].

Project description:In the title polymer, {[La(2)(C(4)H(4)O(6))(3)(H(2)O)(3)]·2H(2)O}(n), two symmetry-independent La(III) ions are nine-coordinated and display a distorted monocapped square-anti-prismatic geometry. One is coordinated by seven O atoms from four tartrate ligands and two water mol-ecules, the other by eight O atoms from five tartrate ligands and one water mol-ecule. The three tartrate ligands in the asymmetric unit act identically as ?(5)-ligands, which link lanthanum centres to form a three-dimensional coordination framework. An extensive network of hydrogen bonds is observed in the crystal structure, involving two uncoordinated water mol-ecules, one of which is disordered over two positions, with occupancies of 0.550?(13) and 0.450?(13).
