Catena-Poly[[bis-[?-2-(3-pyrid-yl)-1H-benzimidazole]-?N:N;?N:N-disilver(I)]-?-2,5-dicarboxy-benzene-1,4-dicarboxyl-ato-?O:O].

ABSTRACT: The title coordination polymer, [Ag(2)(C(10)H(4)O(8))(C(12)H(9)N(3))(2)](n), was prepared by a hydro-thermal method. The Ag(I) atom exists in a strongly distorted trigonal coordination environment. Two Ag(I) ions related by an inversion centre are coordinated by two 2-(3-pyrid-yl)benzimidazole ligands, forming a centrosymmetric cyclic dimer. The bridging bidentate 2,5-dicarboxy-benzene-1,4-dicarboxyl-ate ligand is also located on an inversion centre and connects the binuclear units, generating a one-dimensional polymer. The almost-planar conformation of this ligand allows it to form a strong intra-molecular O-H?O hydrogen bond. Finally, inter-molecular N-H?O hydrogen bonds aggregate the chains into a three-dimensional framework.

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.

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 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 π-π stacking is observed in the crystal structure. One solvent water molecule is disordered equally over two positions.

catena-Poly[[[aqua-(1,10-phenan-throline)cadmium(II)]-μ-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.
