Catena-Poly[[(2,2'-bipyridine-?N,N')nickel(II)]-?-oxalato-?O,O:O,O].

ABSTRACT: The title compound, [Ni(C(2)O(4))(C(10)H(8)N(2))](n), is isostructural with its Mn(II), Fe(II), Cu(II) and Zn(II) analogues. Each Ni(II) atom is chelated by two oxalate ligands and one 2,2'-bipyridine, forming a slightly distorted octa-hedral geometry. Oxlate acts as a bridge to link neighbouring pairs of Ni(II) cations, forming a one-dimensional wave-like chain. The crystal showed partial inversion twinning.

Project description:In the title compound, [Ni(C(14)H(8)O(4))(C(10)H(8)N(2))(H(2)O)(2)](n), the Ni(II) atom is coordinated in a slightly distorted octa-hedral geometry by two water mol-ecules, two N atoms from a 2,2'-bipyridine ligand and two O atoms from the carboxyl-ate groups of two 2,2'-biphenyl-dicarboxyl-ate (2,2'-dpa) ligands. The 2,2'-dpa ligand acts as a bridge between neighbouring Ni(II) atoms, forming one-dimensional coordination polymers along [100]. The coordinated water mol-ecules form hydrogen bonds to the carboxyl-ate O atoms of 2,2'-dpa within the same coordination polymer, and one O-H⋯π inter-action is also formed to 2,2'-dpa.

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:The title compound, [Ni(SO(4))(C(5)H(5)N)(H(2)O)(3)](n), was synthesized by the hydro-thermal reaction of NiSO(4)·6H(2)O, pyridine and water. The central Ni(II) atom is coordinated in a distorted octa-hedral environment by a pyridine N atom, three aqua O atoms and two O atoms of bridging sulfate anions, yielding a zigzag chain. A three-dimensional network is generated via complex hydrogen bonds involving the sulfate and aqua ligands and a pyridine C-H group.

catena-Poly[[(2,2'-bipyrimidine-κN,N)diperchloratocopper(II)]-μ-4,4'-bipyridine-κN:N'].

Project description:The central CuN(4)O(2) motif of the title compound, [Cu(ClO(4))(2)(C(8)H(6)N(4))(C(10)H(8)N(2))](n), exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal centre, showing a considerably long Cu-O bond distance of 2.634 (4) Å towards the second perchlorate group occupying the sixth coordination site, giving a (4+1+1)-type coordination mode. The 4,4'-bipyridine (bipy) ligands are highly twisted with respect to each other, the dihedral angle between the two pyridyl ring planes being 38.9 (2)°. The bipy ligands act as bridging ligands between [Cu(ClO(4))(2)(2,2'-bpym)] (2,2'-bpym is 2,2'-bipyrimidine) units, generating an infinite one-dimensional zigzag chain along [010]. Intra- and intermolecular C-H⋯O hydrogen bonds are present in the crystal structure.

Project description:In the title polymeric compound, [Cd(C(8)H(3)NO(6))(C(10)H(8)N(2))](n), two O atoms from both carboxyl-ate groups of a nitro-phthalate anion coordinate to the Cd(II) cation, forming a seven-membered chelate ring and two carboxyl-ate O atoms from another two nitro-phthalate anions and a 2,2'-bipyridine ligand coordinate to the Cd cation to complete the distorted octa-hedral coordination geometry. The carboxyl-ate groups of the nitro-phthalate anion adopt a syn-anti bridging mode, linking adjacent Cd(II) cations and forming a polymeric chain running along the a axis. Weak intra- and inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

Poly[[diaqua-nickel(II)]-μ(2)-4,4'-bipyridine-κN:N'-μ-p-phenyl-enedioxy-diacetato-κO:O'].

Project description:The title coordination polymer, [Ni(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2)](n), was obtained by the hydro-thermal reaction of nickel(II) sulfate, benzene-1,4-dioxy-diacetic acid (p-phenyl-enedioxy-diacetic acid) and 4,4'-bipyridine (4,4'-bpy) in alkaline aqueous solution. Each Ni(II) atom is coordinated by two O atoms from two benzene-1,4-dioxy-diacetate ligands, two N atoms from two 4,4'-bpy ligands and two water mol-ecules, and displays a distorted octa-hedral geometry. The Ni(II) atom and benzene-1,4-dioxy-diacetate and 4,4'-bpy moieties lie on inversion centres. The benzene-1,4-dioxy-diacetate ligands bridge the Ni(II) atoms to form infinite zigzag chains, which are further inter-connected by 4,4'-bpy ligands to form a grid-like layer parallel to the (01) plane. Moreover, there are O-H⋯O hydrogen-bonding inter-actions within the grid-like layer between the coordinated water mol-ecules and the carboxyl-ate O atoms.

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.

catena-Poly[[(2,2'-bipyridine-κN,N')copper(I)]-μ-cyanido-κC:N-[(2,2'-bipyridine-κN,N')copper(I)]-μ-thio-cyanato-κS:N].

Project description:The title compound, [Cu(2)(CN)(SCN)(C(10)H(8)N(2))(2)](n), contains two crystallographically independent Cu(I) atoms, each in a distorted tetra-hedral geometry. Each Cu atom is coordinated by a bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units to form a binuclear unit. Adjacent binuclear units are connected by a thio-cyanate anion into a one-dimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thio-cyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are π-π inter-actions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].
