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

ABSTRACT: 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 complex, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))](n), the Pb(II) atom is located on a twofold rotation axis and is six-coordinated by four carboxyl-ate O atoms from two 3-methyl-benzoate ligands and two N atoms from two 4,4'-bipyridine (4,4'-bpy) ligands, displaying a hemi-directed coordination. The 4,4'-bpy ligand has an inversion center at the mid-point of the central C-C bond. The Pb(II) atoms are linked by bidentate bridging 4,4'-bpy into a chain along [101]. These chains are further connected into layers via C-H?O hydrogen bonds.

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. Weak C-H⋯O inter-actions between uncoordinated carboxyl-ate O atoms of fumaric acid and water mol-ecules contribute to the crystal packing stability.

Project description:In the title compound, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(4)H(2)O(4))·4H(2)O}(n), the Zn(II) atom is coordinated by two N atoms from two ?-4,4'-bipyridine ligands and four water mol-ecules in a distorted octa-hedral geometry. The coordination unit is extended through the Zn-N bond, leading to a one-dimensional cationic chain. A twofold rotation axis passes through the Zn atom and along the axis of the 4,4'-bipyridine ligand. Each uncoordinated water mol-ecule acts as both hydrogen-bond donor and acceptor. A three-dimensional network is constructed through hydrogen bonds involving water mol-ecules and fumarate dianions.

Project description:In the title compound, [Zn(C(14)H(11)O(2))(2)(C(10)H(8)N(2))(H(2)O)(2)](n), the Zn(II) ion lies on a crystallographic inversion center and is in a slightly distorted octahedral coordination enviroment. 4,4'-Bipyridine ligands act as bridging ligands, connecting Zn(II) ions into a chain along the b-axis direction. In the crystal structure, these chains are linked by inter-molecular O-H?O hydrogen bonds to form a two-dimensional network parallel to the ab plane.

catena-Poly[[[diaqua-cadmium(II)]-bis-[μ-3,5-bis-(isonicotinamido)benzoato]] tetra-hydrate].

Project description:The title compound, {[Cd(C(19)H(13)N(4)O(4))(2)(H(2)O)(2)]·4H(2)O}(n) or {[Cd(BBA)(2)(H(2)O)(2)]·4H(2)O}(n), where BBA is 3,5-bis-(iso-nicotin-amido)-benzoate, is isotypic with its Mn isologue [Chen et al.

The cation sits on a twofold axis and is six-coordinated in a slightly distorted octa-hedral geometry; the polyhedra are linked into zigzag chains, which are further connected by N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds as well as π-π inter-actions [centroid-centroid distance of 3.639 (2) Å], giving a three-dimensional supra-molecular framework.

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.
