Catena-Poly[[[tetra-aqua-cadmium(II)]-?-3,3'-[p-phenyl-enebis(oxymethyl-ene)]bis-(1-pyridinioacetate)] dinitrate hemihydrate].

ABSTRACT: In the title polymeric coordination complex, {[Cd(C(22)H(20)N(2)O(6))(H(2)O)(4)](NO(3))(2)·0.5H(2)O}(n), obtained from the self-assembly of the flexible double betaine 3,3'-[p-phenyl-enebis(oxymethyl-ene)]bis-(1-pyridinioacetate) with cadmium nitrate, both the octa-hedrally coordinated Cd(II) cation and the substituted betaine ligand lie on inversion centres. The chains constructed through the trans-related acetate groups of the ligand are inter-connected via O-H?O hydrogen bonds involving coordinated aqua ligands, the nitrate anions and the partial-occupancy (0.25) water mol-ecule of solvation, forming a three-dimensional structure.

Crystal structure of catena-poly[[di-aqua-cadmium(II)]-μ-3,3'-(1,3-phenyl-ene)diacrylato].

Project description:In the crystal of the title polymeric complex, [Cd(C12H8O4)(H2O)2] n , the Cd(II) cation, located on a twofold rotation axis, is coordinated by two water mol-ecules and chelated by two phenyl-enediacrylate anions (mpda) in a distorted octa-hedral geometry. The mpda anions bridge the Cd(II) cations, forming helical chains propagating along the c-axis direction. The mpba anion has twofold symmetry with two benzene C atoms located on the twofold rotation axis. In the crystal, O-H⋯O hydrogen bonds link the polymeric helical chains into a three-dimensional supra-molecular architecture.

catena-Poly[[[aqua-pyridine-zinc(II)]-μ(2)-3,3'-(p-phenyl-ene)diacrylato] pyridine solvate].

Project description:The title compound, {[Zn(C(12)H(8)O(4))(C(5)H(5)N)(H(2)O)]·C(5)H(5)N}(n), has been prepared by hydro-thermal reaction. The Zn(II) atom is six-coordinated by four carboxyl-ate O atoms of two p-phenylenediacrylate (ppda(2-)) ligands, one N atom of a pyridine mol-ecule and one O atom of a water mol-ecule in a distorted octa-hedral environment. The carboxyl-ate groups of the ppda(2-) anions are in a bridging-chelating mode, in which two O atoms chelate one Zn(2+) ion. These connections result in an extended chain structure. Parallel packing of the chains forms a two-dimensional network with inter-molecular edge-to-face inter-actions. Further linkages between the layers through O-H⋯O hydrogen-bonding inter-actions result in a three-dimensional supra-molecular architecture with one-dimensional recta-nglar channels.

3,3'-[1,2-Phenyl-enebis(methyl-ene)]bis-(1-propyl-benzimidazolium) dibromide hemihydrate.

Project description:The asymmetric unit of the title compound, C(28)H(32)N(4) (2+)·2Br(-)·0.5H(2)O, contains one 3,3'-[1,2-phenyl-enebis(methyl-ene)]bis-(1-propyl-benzimidazolium) cation, two bromide anions and one half-mol-ecule of water. In the crystal, the whole 3,3'-[1,2-phen-yl-enebis(methyl-ene)]bis-(1-propyl-benzimidazolium) cation and one of the bromide anions are each disordered over two positions with site-occupancy ratios of 0.751?(6):0.249?(6) and 0.680?(8):0.320?(8). For the major component of the disordered cation, the central benzene ring forms dihedral angles of 83.6?(5) and 88.2?(4)° with its adjacent imidazole rings, while these angles for the minor component are 89.2?(15) and 84.9?(13)°. In the crystal, the cations and anions are linked by C-H?Br hydrogen bonds into dimers and then stacked along the c axis. The crystal packing is further stabilized by C-H?? and ?-? inter-actions [shortest centroid-centroid distance = 3.646?(4)?Å].

catena-Poly[[[aqua-(1,10-phenanthro-line)zinc(II)]-?-3,3'-(p-phenyl-ene)di-acrylato] hemihydrate].

Project description:In the title compound, {[Zn(C(12)H(8)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5H(2)O}(n), each Zn(II) atom is six-coordinated by two N atoms from one 1,10-phenanthroline (phen), three carboxyl-ate O atoms from two different L ligands [H(2)L = 3,3'-(p-phenyl-ene)diacrylic acid] and one water mol-ecule in a distorted octa-hedral environment. The two L dianions are situated across inversion centres and bridge neighbouring Zn(II) centres, yielding a chain propagating parallel to [100]. O-H?O hydrogen bonds between the coordinated water molecule, the solvent water molecule (half-occupied) and the carboxylate O atoms further stabilize the structure.

catena-Poly[[[tetra-aqua-cadmium(II)]-μ-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.

Project description:In the title compound, {[Ni(C(10)H(8)N(2))(H(2)O)(4)](C(12)H(8)O(4))}(n), the Ni(II), 4,4'-bipyridyl (bipy) and 3,3'-(p-phenyl-ene)diacrylate (L(2-)) moieties are situated on inversion centres. The bipy ligands bridge Ni(II) ions into positively charged polymeric chains along [101]. The Ni(II) atom is coordinated by two N atoms from two bipy ligands and four water mol-ecules in a distorted octa-hedral geometry. L(2-) anions inter-act with the polymeric chains via O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

catena-Poly[[cadmium-bis-(μ-triethyl-ene-tetra-mine-κN,N':N'',N''')-cadmium-(μ-triethyl-ene-tetra-mine-κN,N':N'',N''')] hexa-fluoridogermanate].

Project description:The title fluoridogermanate, {[Cd(2)(C(6)H(18)N(4))(3)][GeF(6)]}(n), was synthesized hydro-thermally. The crystal structure comprises undulated cationic [Cd(2)(TETA)(3)](4+) chains (TETA is triethyl-ene-tetra-mine) propagating parallel to [101]. The central Cd(II) atom is six-coordinated in a CdN(6) set by three TETA ligands. The isolated [GeF(6)](2-) units, serving as counter-anions, occupy the inter-chain spaces and simultaneously link adjacent chains into a three-dimensional network through extensive N-H⋯F hydrogen-bonding inter-actions. One of the ethyl-ene bridges of one TETA ligand is disordered around a twofold rotation axis.

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.
