Poly[[μ(2)-2,2'-diethyl-1,1'-(butane-1,4-di-yl)diimidazole-κN:N](μ(2)-5-hydroxy-isophthalato-κO:O)zinc].

ABSTRACT: In the title coordination polymer, [Zn(C(8)H(4)O(5))(C(14)H(22)N(4))](n), the Zn(II) cation is coordinated by an O(2)N(2) donor set in a distorted tetra-hedral geometry. The Zn(II) ions are linked by μ(2)-OH-bdc (OH-H(2)bdc = 5-hy-droxy-isophthalic acid) and bbie ligands [bbie = 2,2'-diethyl-1,1'-(butane-1,4-di-yl)diimidazole], forming a two-dimensional layer parallel to the ab plane. The layers are further connected through intermolecular C-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional supramolecular structure. In the bbie ligand, the two C atoms in the ethyl group are each disordered over two positions with a site-occupancy ratio of 0.69:0.31.

catena-Poly[[aqua-(2,2'-bipyridine-κN,N')copper(II)]-μ-5-nitro-isophthalato-κO,O:O].

Project description:In the asymmetric unit of the title compound, [Cu(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)](n), there are two symmetry-independent one-dimensional coordination polymers related by a non-crystallographic inversion center. Within the polymers, the Cu(II )atoms, coordinated by the water mol-ecule and the chelating 2,2'-bipyridine ligands, are bridged by 5-nitro-benzene-1,3-dicarboxyl-ate dianions which act as tridentate ligands; the carboxyl-ate groups exhibit monodentate and symmetric bidentate coordination modes. The Cu(II) atoms show a strongly distorted octa-hedral coordination geometry. In the crystal structure, the two symmetry-independent coordination polymers form another one-dimensional polymeric structure via O-H⋯O hydrogen bonds between coordinated water mol-ecules and carboxyl-ate groups.

Project description:In the title compound, [Zn(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)(3)]·H(2)O, the Zn(II) cation is hexa-coordinated by a chelating 2,2'-bipyridine ligand, one carboxyl-ate O atom from a 5-nitro-isophthalate dianion and three water mol-ecules in a slightly distorted octa-hedral geometry. The structure contains isolated neutral complexes, in contrast to coordination polymers formed by Mn(II), Co(II) and Cu(II) with the same ligand set. An extensive network of hydrogen bonds is formed between the water mol-ecules and the carboxyl-ate groups.

Poly[[(μ-2,2'-bipyrimidine-κN,N:N,N)(μ-sulfato-κO:O')zinc(II)] monohydrate].

Project description:In the title compound, {[Zn(SO(4))(C(8)H(6)N(4))]·H(2)O}(n), the Zn(II) atom is in a distorted octa-hedral environment. The Zn(II) atoms are bridged by both 2,2'-bipyrimidine and sulfate ligands, thus forming a three-dimensional polymeric metal-organic solid that contains uncoordinated water mol-ecules in the inter-stitial space. O-H⋯O hydrogen bonding consolidates the crystal structure.

Bis[μ-2,2'-dimethyl-1,1'-(oxydiethyl-ene)bis-(1H-benzimidazole)-κN:N]bis-[bis-(4-methoxy-benzoato-κO,O')cadmium(II)].

Project description:The title complex, [Cd(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], forms a dimer of the paddle-wheel type, located on a crystallographic inversion centre. The Cd(II) ion is hexa-coordinated by four carboxylate O atoms [Cd⋯O = 2.280 (2)-2.404 (2) Å] from two chelating 4-methoxy-benzoate anions, and two N atoms [Cd⋯N = 2.313 (2) and 2.332 (2) Å] from one chelating 2,2'-dimethyl-3,3'-(oxydiethyl-ene)bis-(1H-benzimidazole) ligand. In the crystal, mol-ecules are linked by a weak inter-molecular C-H⋯O hydrogen bond and an inter-molecular C-H⋯π inter-action.

catena-Poly[[[bis-(4-amino-benzoato-κO)copper(II)]-μ-1,1'-(pentane-1,5-di-yl)diimidazole] trihydrate].

Project description:In the title compound, {[Cu(C(7)H(6)NO(2))(2)(C(11)H(16)N(4))]·3H(2)O}(n), each Cu(II) atom is coordinated by two O atoms from two 4-amino-benzoate anions, and two N atoms from two different 1,1'-(pentane-1,5-di-yl)diimidazole (biim-5) ligands, to furnish a distorted square-planar geometry. The biim-5 ligand coordinates to two copper(II) cations, acting as a bridging ligand; as a result the copper(II) cations are connected to form an infinite chain structure. The polymeric chains are linked through a variety of hydrogen bonds to form a three-dimensional structure.

catena-Poly[[(2,2':6',2''-terpyridine-κN,N',N'')zinc(II)]-μ-2,2'-oxydibenzo-ato-κO:O'].

Project description:In the title compound, [Zn(C(14)H(8)O(5))(C(15)H(11)N(3))](n), both the Zn(II) ion and the oxydibenzoate ligand are located on a twofold rotation axis. The Zn(II) centre is coordinated by three N atoms from a chelating 2,2':6',2''-terpyridine ligand and two O atoms from two 2,2'-oxydibenzoate ligands, forming a distorted trigonal-bipyramidal coordination environment. Further coordination via the 2,2'-oxydibenzoate anions forms a one-dimensional coordination polymer extending parallel to [010]. Aromatic π-π stacking inter-actions are observed between adjacent terpyridine ligands with a centroid-centroid distance of 3.568 (2) Å.

Bis(μ-3-hydroxy-benzoato-κO,O':O)bis-[aqua-(3-hydroxy-benzoato-κO,O')(1,10-phenanthroline-κN,N')lead(II)] monohydrate.

Project description:In the centrosymmetric binuclear title complex, [Pb(2)(C(7)H(5)O(3))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, each Pb atom is eight-coordinated in a PbO(6)N(2) environment by two N atoms from the 1,10-phenanthroline (phen) ligand, five carboxylate O atoms from four 3-hydroxy-benzoate anions and one O atom from the coordinated water mol-ecule in a distorted bicapped trigonal-prismatic geometry. The benzoate groups coordinate each Pb(II) atom in two different ways. Two benzoate ions behave as bidentate ligands to the Pb atom, and another benzoate ion bridges the Pb atoms, forming a binuclear structure. The dimeric units are packed via O-H⋯O hydrogen bonds and π-π inter-actions between the aromatic rings of neighboring mol-ecules, with centroid-centroid distances of 3.552 (2) and 3.641 (2) Å.

catena-Poly[[(4-methyl-benzoato-κO)manganese(II)]-μ-aqua-bis-(μ-4-methyl-benzoato-κO:O')[(4-methyl-benzoato-κO)manganese(II)]-bis-(μ-N,N-diethyl-nicotinamide)-κN:O;O:N].

Project description:The asymmetric unit of the title complex, [Mn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)(H(2)O)](n), contains two crystallographically independent units. In each one, the Mn(II) ions are bridged by two 4-methyl-benzoate (PMB) ligands and one water mol-ecule. In the crystal structure, each Mn(II) ion is coordinated by three PMB ligands, one water mol-ecule and two symmetry-related N,N-diethyl-nicotinamide (DENA) ligands. Symmetry-related Mn(II) ions are bridged by the N and O atoms of symmetry-related DENA ligands, forming polymeric chains parallel to [100]. The coord-ination environmnts for the Mn(II) ions are slightly distorted octa-hedral. Intra-molecular O-H⋯O hydrogen bonds link bridging water mol-ecules to the carboxyl-ate O atoms of a neigh-boring polymeric chain. In the crystal structure, π-π contacts between benzene rings [centroid-centroid distance = 3.562 (1) Å] and weak C-H⋯π inter-actions are also observed.
