Poly[bis-(?(2)-4,4'-bipyridine)bis-(3-nitro-benzoato)cobalt(II)].

ABSTRACT: The hydro-thermal reaction of cobalt nitrate with 4,4'-bipyridine and 3-nitro-benzoic acid lead to the formation of the title complex, [Co(C(7)H(4)NO(4))(2)(C(10)H(8)N(2))(2)](n). In the crystal structure, the Co(II) atoms are coordinated by two terminal carboxyl-ate anions and four 4,4'-bipyridine ligands within slightly distorted octa-hedra. The Co(II) atom and one of the two independent 4,4'-bipyridine ligands are located on a twofold rotation axis, while the second independent 4,4'-bipyridine mol-ecule is located on a centre of inversion. One of the two rings of one 4,4'-bipyridine ligand is disordered over two orientations and was refined using a split model [occupancy ratio 0.68?(2):0.32?(2)]. The Co(II) atoms are connected by the 4,4'-bipyridine ligands into layers, which are located parallel to the ab plane.

Project description:The crystal structure of the title complex, [Ni(C(7)H(4)NO(4))(2)(C(10)H(8)N(2))(2)](n), exhibits a two-dimensional network, which is built up from slightly distorted NiN(4)O(2) polyhedra (2 symmetry), bipyridine ligands, and carboxyl-ate anions.

(?-4,4'-Bipyridine-?N:N')bis-[triaqua-(4,4'-bipyridine-?N)(3-nitro-phthalato-?O)cobalt(II)].

Project description:The title binuclear complex, [Co(2)(C(8)H(3)NO(6))(2)(C(10)H(8)N(2))(3)(H(2)O)(6)], has been synthesized hydro-thermally from 3-nitro-phthalic acid (H(2)NPA), Co(NO(3))(2)·6H(2)O and 4,4'-bipyridine (4,4'-bipy). The mol-ecule of the complex occupies a special position on an inversion centre. The Co(II) atom has a slightly distorted octa-hedral environment formed by two N atoms from two 4,4'-bipy ligands, one carboxyl-ate O atom from NPA, and three O atoms of water mol-ecules. An extensive O-H?O and N-H?O hydrogen-bonding system links mol-ecules of the complex into a three-dimensional network.

Project description:In the title complex, {[Co(NCS)(2)(C(10)H(8)N(2))(H(2)O)(2)]·C(10)H(8)N(2)}(n), the Co(II) ion is located on an inversion centre and is coordinated by two N atoms from the two 4,4'-bipyridine ligands, two O atoms from the water mol-ecule, and two N atoms from two isothio-cyanate ions in a distorted octa-hedral environment. In the crystal, the coordinated water mol-ecules, isothio-cyanate ions and solvent 4,4'-bipyridine mol-ecules are linked by O-H?S and O-H?N hydrogen bonds into layers parallel to the ab plane.

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.

Project description:In the title compound, [Co(C(9)H(5)O(6))(2)(C(10)H(8)N(2))](n), the asymmetric unit consists of one Co(2+) ion with site symmetry 2, one mono-deprotonated 1,3,5-benzene-tricarboxylic acid anion and one-half of a 4,4'-bipyridine (4,4'-bipy) mol-ecule, in which two N and two C atoms have site symmetry 2. In the crystal structure, the Co(2+) centre is coordinated by four O atoms from two bidentate carboxyl-ate groups of two anions and two N atoms of two 4,4'-bipy mol-ecules, resulting in infinite chains propagating in [010]. The cobalt coordination is distorted trans-CoO(4)N(2) octa-hedral and inter-chain O-H?O hydrogen bonds complete the structure.

The bipyridine ligands also lies on a twofold rotation axis and bridge the Co(II) ions, forming chains extending along [010]. An intra-chain O-H?O hydrogen bond is observed.

catena-Poly[[[bis-(4-methyl-benzoato-?O,O')zinc(II)]-?-4,4'-bipyridine-?N:N'] tetra-hydrate].

Project description:The asymmetric unit of the title compound, {[Zn(C(7)H(7)O(2))(2)(C(10)H(8)N(2))]·4H(2)O}(n), contains a highly distorted octa-hedral Zn(II) metal center strongly coordinated by two N atoms of two 4,4'-bipyridine (4,4'-bipy) ligands and chelated by two 4-methyl-benzoate anions. The crystallographic inversion center and glide plane present at the center of the C-C single bond of 4,4'-bipy, along with the cis coordination motif of the 4,4'-bipy, lead to one-dimensional zigzag chains. There are a large number of water mol-ecules in the crystal structure, which also form one-dimensional chains through O-H?O hydrogen bonds.

Project description:In the title compound, [Co(C(2)H(2)N(3))(C(7)H(4)NO(4))](n), the Co(II) atom is five-coordinated by three triazolate ligands and one bidentate 3-nitro-benzoate anion in a distorted trigonal-bipyramidal geometry. The triazolate ligand bridges the Co(II) atoms, generating a two-dimensional net parallel to the ab plane, in which both the Co(II) atom and the triazolate ligand act as three-connected nodes. Two weak inter-molecular C-H?O hydrogen bonds connect the nets.
