Poly[tetra-aqua-di-?(4)-malonato-barium(II)cadmium(II)].

ABSTRACT: In the title complex, [BaCd(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Ba(II) atoms, located on crystallographic twofold axes, adopt slightly distorted square-anti-prismatic coordination geometries, while the Cd(II) atoms, which lie on crystallographic centres of symmetry, have a distorted octa-hedral coordination. Each malonate dianion binds two different Cd(II) atoms and two different Ba(II) atoms. This connectivity generates alternating layers along [100] in the structure, with one type containing Cd(II) cations and malonate dianions, while the other is primarily composed of Ba(II) ions and coordinated water mol-ecules. The water mol-ecules also participate in extensive O-H?O hydrogen bonding.

Poly[di-?-aqua-diaqua-di-?(6)-malonato-cobalt(II)dipotassium(I)].

Project description:In the title complex, [CoK(2)(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Co atom is located on a position with site symmetry 2/m, the K atom and one water mol-ecule are located on a mirror plane, and the malonate and one water mol-ecule are located on a twofold rotation axis. The K(I) atom is seven-coordinated by four carboxyl-ate O atoms from four malonate ligands and by three water O atoms, forming a distorted polyhedron. The Co(II) atom is in an almost octa-hedral environment formed by four carboxyl-ate O atoms from two malonate ligands and two water O atoms. The structure consists of layers parallel to (20[Formula: see text]) built up from edge-sharing KO(7) and CoO(6) polyhedra, which are connected by O-H?O hydrogen bonding including 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.

catena-Poly[[[tetra-aqua-cadmium(II)]-?-4,4'-bipyridine] fumarate tetra-hydrate].

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[[[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.

Monoclinic polymorph of poly[[di-?-aqua-triaquadi-?-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.

?-Pyrazine-bis-[tetra-aqua-cadmium(II)] ?-pyrazine-bis-[tetra-acetato-cadmium(II)].

Project description:In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the acetate groups and water mol-ecules lie across the inter-secting mirror planes. Each Cd(II) atom in the cation is five-coordinated by four O atoms from four water mol-ecules and one N atom from the bridging pyrazine ligand, whereas each Cd(II) in the anion is nine-coordinated by four pairs of O atoms from the bidentate acetate ligands and one N atom from the bridging pyrazine ligand. In the crystal structure, each anion is surrounded by eight nearest-neighbour cations and vice versa. The crystal structure is stabilized by ionic inter-actions as well as by C-H?O inter-actions.

catena-Poly[[[aqua-(5-nitro-benzene-1,2,3-tricarboxyl-ato-?O)nickel(II)]-di-?-aqua-[diaqua-sodium]-di-?-aqua] tetra-hydrate].

Project description:In the title complex, {[NaNi(C(9)H(2)NO(8))(H(2)O)(7)]·4H(2)O}(n), the Ni(II) atom has a distorted octa-hedral coordination, defined by five O atoms from five water mol-ecules and one O atom from one 5-nitro-benzene-1,2,3-tricarboxyl-ate ligand. The Na cation is coordinated by six water O atoms in an irregular trigonal-prismatic geometry. There are seven coordinated water mol-ecules in the asymmetic unit. The Ni and Na atoms are linked by water bridges, forming infinite chains, which are connected by strong O-H?O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules into a three-dimensional network.

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

Project description:In the title polymeric complex, [Cd(C(5)H(3)N(6))(C(2)O(4))(0.5)(H(2)O)](n), the Cd(II) ion is coordinated by four O atoms and three N atoms from two 5-(pyrazin-2-yl)tetra-zolate ligands, two oxalate ligands and one water mol-ecule, displaying a distorted monocapped octa-hedral geometry. The bridging ligands link metal centres, forming a three-dimensional network which is stabilized by inter-molecular O-H?N hydrogen-bonding inter-actions.
