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

ABSTRACT: 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.

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.

Project description:In the title coordination polymer, [Zn(C(8)H(4)O(4))(C(5)H(5)N)(2)](n), the Zn(II) atom, located on a twofold rotation axis, is tetra-coordinated by two monodentate O atoms from two different carboxyl-ate groups and two pyridyl N atoms, forming a distorted tetra-hedral geometry.

Project description:The title compound, {[NdPt(CN)(4)(NO(3))(C(15)H(11)N(3))(H(2)O)(2)]·CH(3)CN·0.5C(15)H(11)N(3)}(n), was isolated from solution as a one-dimensional coordination polymer. The Nd(3+) site in the structure has a ninefold coordination with a distorted tricapped trigonal-prismatic geometry, while the Pt(II) ion is coordinated by four cyanide groups in an almost regular square-planar geometry. Cis-bridging by the tetracyanidoplatinate anions links the Nd(3+) cations, forming the one-dimensional chains. Additionally, each Nd(3+) contains coordin-ation by two water mol-ecules, one tridentate 2,2':6',2''-terpyridine mol-ecule, and one bidentate nitrate anion. 2,2':6',2''-Terpyridine and acetonitrile solvent mol-ecules are incorporated between the chains, the former form π-stacking inter-actions (average inter-planar distance 3.33 Å) with terpyridine mol-ecules located in the chains. Relatively long Pt⋯Pt inter-actions [3.847 (1) Å] are observed in the structure. O-H⋯N and O-H⋯O hydrogen bonding interactions between the consituents consolidates the crystal packing.

Weak C-H⋯O inter-actions contribute to the crystal packing stability.

The Co(2+) ion is six-coordinated in a strongly distorted octa-hedral geometry. The chains are connected to each other by a network of O-H⋯O hydrogen bonds involving solvent water mol-ecules.

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.
