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

ABSTRACT: 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-?-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.

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

Project description: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.

Project description:In polymeric title compound, {[Co(2)(C(7)H(2)N(2)O(7))(2)(H(2)O)(6)]·2H(2)O}(n), obtained from the reaction of 3,5-dinitro-salicylic acid with cobalt(II) acetate, both Co(II) atoms are located on inversion centres and exhibit a distorted octahedral coordination geometry. The coordin-ation sphere about one Co(II) atom comprises four O-atom donors from two bidentate chelate (O(phenolate) and O(carbox-yl)) and bridging dianionic ligands and two water mol-ecules [Co-O range = 2.0249?(11)-2.1386?(14)?Å], while that about the second Co(II) atom has four water mol-ecules and two bridging carboxyl-ate O-donor atoms [Co-O range = 2.0690?(14)-2.1364?(11)?Å]. The coordinated water mol-ecules as well as the water mol-ecules of solvation give O-H?O water-water and water-carboxyl hydrogen-bonding inter-actions in the three-dimensional framework structure.

Poly[(?-3,5-dinitro-benzoato)(?-3,5-dinitro-benzoic acid)rubidium].

Project description:The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))(C(7)H(4)N(2)O(6))](n), comprises an Rb(+) cation, a 3,5-dinitro-benzoate anion and a 3,5-dinitro-benzoic acid ligand. The Rb(+) cation is nine-coordinated by O atoms from four 3,5-dinitro-benzoate anions and three neutral 3,5-dinitro-benzoic acid ligands. The metal atom is firstly linked by four bridging carboxyl groups, forming a binuclear motif, which is further linked by the nitro groups into a two-dimensional framework along the [110] direction. A short O-H?O hydrogen bond between two adjacent carboxy/carboxylate groups occurs.

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[triaqua-μ(4)-pyridine-3,5-dicarboxyl-ato-barium(II)].

Project description:The reaction of the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) with Ba(NO(3))(2) leads to the formation of the title polymeric compound, [Ba(C(7)H(3)NO(4))(H(2)O)(3)](n). The Ba(II) atom is nine-coordinated by six carboxyl-ate O atoms from the (py-3,5-dc)(2-) ligands, and three O atoms from the coordinated water mol-ecules. The coordination polyhedron around the Ba(II) atom is best described as tricapped trigonal-prismatic. In the crystal structure, inter-molecular inter-actions, such as X-H⋯O hydrogen bonds (X = O and C) and π-π stacking [centroid-centroid distances between pyridine rings of 3.6191 (13) and 3.6192 (13) Å] play an important role in stabilizing the supramolecular structure.

catena-Poly[[[aqua-copper(II)]-bis-[μ-bis-(3,5-dimethyl-1H-pyrazol-4-yl) selenide-κN:N]] dichloride monohydrate].

Project description:In the title compound, {[Cu(C(10)H(14)N(4)Se)(2)(H(2)O)]Cl(2)·H(2)O}(n), the Cu(II) ion, lying on a twofold rotation axis, has a square-pyramidal geometry constituted by four N atoms of pyrazolyl groups in the basal plane and an apical O atom of a water mol-ecule. A pair of bis-(3,5-dimethyl-1H-pyrazol-4-yl) selenide ligands bridge the Cu centers into a polymeric double-chain extending along [001]. The chloride anions are involved in inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds, which link the chains into a three-dimensional network.

Poly[(μ-3,5-dinitro-2-oxidobenzoato)(μ-3-hydroxy-pyridine)copper(II)].

Project description:A new coordination polymer, [Cu(C(7)H(2)N(2)O(7))(C(5)H(5)NO)](n), exhibits a double-chain structure, in which 3,5-dinitro-2-oxidobenzoate and 3-hydroxy-pyridine both act as bridging ligands, -connecting adjacent copper(II) centers to form an infinite double-stranded chain. The asymmetric unit contains one Cu(II) ion, one 3,5-dinitro-2-oxidobenzoate ligand and a 3-hydroxy-pyridine ligand. Coordination by one N atom and three O atoms from two different 3,5-dinitro-2-oxidobenzoate ligands and a 3-hydroxy-pyridine ligand creates a square-planar Cu(II) center, which is augmented by a less tightly bonded fifth phenol O atom to form a square-pyramidal five-coordinate complex with an essentially planar base. The double-stranded chains are stabilized by intra-chain π-π inter-actions [the centroid-to-centroid distance between adjacent aromatic rings is 3.719 (7) Å], and further linked through O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.
