Catena-Poly[[[tetra-aqua-nickel(II)]-?-4,4'-bipyridyl-?N:N'] 3,3'-(p-phenyl-ene)diacrylate].

ABSTRACT: 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[[[tetra-aqua-copper(II)]-?-4,4'-bipyridyl-?(2)N:N'] tetra-fluorido-succinate tetra-hydrate].

Project description:In the title compound, {[Cu(C(10)H(8)N(2))(H(2)O)(4)](C(4)F(4)O(4))·4H(2)O}(n), the Cu(II) atom adopts an elongated octa-hedral geometry because of the Jahn-Teller effect. Both cation and anion have crystallographic twofold rotation symmetry with the twofold axes passing through the Cu and N atoms and through the midpoint of the central C-C bond. The 4,4'-bipyridyl ligand links the Cu(II) atoms into a linear chain along the b axis. O-H?O hydrogen-bonding inter-actions between the cationic chains and the tetra-fluorido-succinate anions and the free water mol-ecules generate a three-dimensional supra-molecular network.

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

Project description: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.

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.

?-Biphenyl-3,3',4,4'-tetra-carboxyl-ato-?O:O-bis-[triaqua-(2,2'-bipyridyl-?N,N')nickel(II)] hexa-hydrate.

Project description:The asymmetric unit of the title complex, [Ni(2)(C(16)H(6)O(8))(C(10)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains one Ni(II) atom, one 2,2'-bipyridine ligand, three coordinated water mol-ecules, one-half of a fully deprotonated biphenyl-3,3',4,4'-tetra-carboxyl-ate anion and three lattice water mol-ecules. The Ni(II) atom displays a distorted NiN(2)O(4) octa-hedral coordination formed by one carboxyl-ate O atom, three water O atoms and two N atoms of the chelating ligand. The complete biphenyl-3,3',4,4'-tetra-carboxyl-ate ligand displays inversion symmetry and links two symmetry-related Ni(II) atoms into a binuclear complex. Neighbouring complex mol-ecules are linked through O-H?O hydrogen bonds into a three-dimensional structure. Additional O-H?O hydrogen bonds between the lattice water mol-ecules help to consolidate the crystal packing.

catena-Poly[[tetra-aqua-nickel(II)]-?-(9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carboxyl-ato)-?(2)O(1):O(8)-[tetra-aqua-nickel(II)]-?-4,4'-bipyridine-?(2)N:N'].

Project description:In the crystal of the title polymeric complex, [Ni(2)(C(18)H(4)O(10))(C(10)H(8)N(2))(H(2)O)(8)](n), each Ni(II) cation is coord-in-ated by four water mol-ecules in the equatorial plane, and is further bridged by an 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carb-oxy-l-ate anion and a 4,4'-bipyridine ligand in the axial directions, forming a distorted octa-hedral geometry. The 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carboxyl-ate anion is centrosymmetric with the centroid of the quinone ring located about an inversion center; the 4,4'-bipyridine ligand is also centrosymmetric with the mid-point of the C-C bond linking two pyridine rings located about another invertion center. The 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carboxyl-ate anion and bypiridine ligand bridge the Ni(II) cations, forming a polymeric chain along the b axis. ?-? stacking is observed between pyridine and benzene rings [centroid-centroid distance = 3.705?(2)?Å]. All of the coordinating water mol-ecules are involved in O-H?O hydrogen bonding.

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.

Crystal structure of catena-poly[[di-aqua-cadmium(II)]-?-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.

Poly[[aqua-(?-4,4'-bipyridyl-?N:N')bis-(?-formato-?O:O')iron(II)] tetra-hydrate].

Project description:In the title compound, {[Fe(CHO(2))(2)(C(10)H(8)N(2))(H(2)O)]·4H(2)O}(n), the Fe(II) ion is coordinated by two 4,4'-bipyridyl (4,4'-bpy) ligands, three formate ligands and one water molecule. The slightly distorted octahedral FeN(2)O(4) coordination results from the N atoms of two bridging 4,4'-bpy ligands, the O atoms of two bridging HCOO(-) anions of anti-anti mode, all in trans positions around the metal centre, and the O atoms of one terminal HCOO(-) anion and of one water molecule. The bridging formate ligands link the metal ions into chains that are further connected via 4,4'-bpy ligands into a framework structure. The three-dimensional structure is stabilized by extensive O-H?O hydrogen bonding. The crystals were twinned containing a 0.84:0.16 racemate.
