Catena-Poly[[bis-(1H-imidazole-?N)copper(II)]-?-benzene-1,4-dicarboxyl-ato-?O:O].

ABSTRACT: In the title compound, [Cu(C(8)H(4)O(4))(C(3)H(4)N(2))(2)](n), the Cu(II) atom is four-coordinated by two carboxyl-ate O atoms from two different terephthalate ligands and two N atoms from two imidazole ligands in a slightly distorted square-planar coordination environment. Each terephthalate ligand acts as a bis-monodentate ligand that binds two Cu(II) atoms, thus forming two unique chains extending parallel to [110]. The imidazole ligands are attached on both sides of the chains.

Project description:In the title compound, {[Cu(C(12)H(6)O(4))(C(3)H(4)N(2))(2)(H(2)O)]·2H(2)O}(n), the Cu(II) cation is coordinated by two naphthalene-1,4-dicarboxyl-ate (naph) dianions, two imidazole mol-ecules and one water mol-ecule in a distorted square-pyramidal geometry. The Cu-O bond distance in the apical direction is 0.509?(3)?Å longer than the mean Cu-O bond distance in the basal plane. The naph dianion bridges two Cu(II) cations, forming a one-dimensional polymeric chain. The coordinated water mol-ecule is hydrogen-bonded to the carboxylate groups and imidazole ligands of adjacent polymeric chains, forming a three-dimensional supra-molecular structure. No ?-? stacking is observed in the crystal structure. One solvent water molecule is disordered equally over two positions.

Project description:In the title compound, [Cu(C(8)H(4)O(4))(C(12)H(11)N(5))(2)(H(2)O)](n), the Cu(II) ion is five-coordinated by two carboxyl-ate O atoms from two symmetry-related benzene-1,4-dicarboxyl-ate ligands, two N atoms from two symmetry-related N(6)-benzyl-adenine ligands and one water O atom in a square-pyramidal environment. The Cu(II) and water O atoms lie on a twofold rotation axis, and the benzene-1,4-dicarboxyl-ate ligand lies on an inversion center. The water O atom occupies the apical position and the basal plane is occupied by two O atoms and two N atoms. Each benzene-1,4-dicarboxyl-ate anion acts as a bis-monodentate ligand that binds two Cu(II) cations, forming an infinite chain extending parallel to [001]. The N(6)-benzyl-adenine ligands are attached on both sides of the chain. Neighboring chains are further inter-connected into the resulting three-dimensional supra-molecular architecture via O-H?O, N-H?O and N-H?N hydrogen bonds.

catena-Poly[[[aqua-(1,10-phenan-throline)cadmium(II)]-?-benzene-1,4-dicarboxyl-ato] benzene-1,4-dicarboxylic acid hemisolvate].

Project description:A new cadmium(II) coordination polymer, {[Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5C(8)H(6)O(4)}(n), has been synthesized under hydro-thermal conditions. The asymmetric unit contains one Cd(II) atom, one benzene-1,4-dicarboxyl-ate anion, one 1,10-phenanthroline ligand, one coordinated water mol-ecule and half of an uncoordinated benzene-1,4-dicaboxylic acid solvent mol-ecule. The Cd(II) atom is in the centre of a monocapped distorted octa-hedron made up of four O atoms of two chelating benzene-1,4-dicarboxyl-ate anions, one water O atom and two 1,10-phenanthroline N atoms. The metal centres are connected via bis-chelating benzene-1,4-dicarboxyl-ate anions into a zigzag chain structure along [001]. These chains are further connected by O-H?O hydrogen bonds between the water mol-ecules and adjacent carboxyl-ate O atoms. Additional O-H?O hydrogen bonding between the uncoordinated benzene-1,4-dicaboxylic acid mol-ecules along [010] consolidates the structure.

Poly[[tetra-aqua-bis-(?(3)-1H-imidazole-4,5-dicarboxyl-ato)tetra-kis-(?(2)-1H-imidazole-4,5-dicarboxyl-ato)tricobalt(II)diytterbium(III)] dihydrate].

Project description:The asymmetric unit of the title compound, {[Co(3)Yb(2)(C(5)H(2)N(2)O(4))(6)(H(2)O)(4)]·2H(2)O}(n), contains one Yb(III) ion, two Co(II) ions (one situated on an inversion centre), three imidazole-4,5-dicarboxyl-ate ligands, two coordinated water mol-ecules and one uncoordinated water mol-ecule. The Yb(III) ion is seven-coordinated, in a monocapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxyl-ate ligands and one water O atom. Both Co(II) ions are six-coordinated in a slightly distorted octa-hedral geometry. The Co(II) ion that is located on an inversion center is coordinated by two O atoms from two water mol-ecules, as well as two O atoms and two N atoms from two imidazole-4,5-dicarboxyl-ate ligands. The second Co(II) ion is bonded to four O atoms and two N atoms from four imidazole-4,5-dicarboxyl-ate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate ligands, generating a three-dimensional network. The crystal structure is further stabilized by N-H?O, O-H?O and C-H?O hydrogen-bonding inter-actions involving the water mol-ecules and the imidazole-4,5-dicarboxyl-ate ligands.

Poly[tris-(2,5-dimethyl-benzene-1,4--dicarboxyl-ato)bis-(pyridine)trizinc(II)].

Project description:The asymmetric unit of the title polymeric compound, [Zn(3)(C(10)H(8)O(4))(3)(C(5)H(5)N)(2)](n) or [Zn(3)(dmbdc)(3)(py)(2)](n) (dmbdc = 2,5-dimethyl-benzene-dicarboxyl-ate; py = pyridine) contains two Zn(II) ions, one of which is located on an inversion centre, one and a half 2,5-dimethyl-benzene-dicarboxyl-ate ligands and one pyridine ligand. Each ZnO(6) octa-hedron is sandwiched between two ZnO(4)N square-pyramids, forming a trinuclear zinc secondary building unit (SBU); each SBU is further linked by six 2,5-dimethyl-benzene-dicarboxyl-ate ligands with six adjacent trinuclear zinc SBU's, forming a two-dimensional layer structure with a (3,6) net. One of the three zinc ions is octa-hedrally coordinated and the other two are square-pyramidally coordinated. The coordination modes for 2,5-dimethyl-benzene-dicarboxyl-ates are bis-(bidentate) or bidentate-tridentate.
