Catena-Poly[[aqua-(2,2'-bipyridyl)cobalt(II)]-μ-5-nitro-isophthalato].

ABSTRACT: In the crystal structure of the title compound, [Co(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, which are approximately related by noncrystallographic inversion symmetry. Each zigzag chain is constructed from one Co(II) ion, one O-monodentate 5-nitro-isophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water mol-ecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN(2)O(4) octa-hedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-H⋯O hydrogen bonds arising from the water mol-ecules complete the structure.

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, [Co(C(14)H(8)N(2)O(6))(H(2)O)(4)](n), each 5,5'-diazenediylbis(2-hydroxy-benzoato) ligand acts as a dicarboxyl-ate bridge, leading to the formation of polymeric chains running in the [10] direction. The Co atom is hexa-coordinated in a distorted octa-hedral geometry by six O atoms [Co-O = 2.039 (4)-2.115 (4) Å] from two ligands and four water mol-ecules. Inter-molecular O-H⋯O and O-H⋯N hydrogen bonds build up a three-dimensional supra-molecular structure.

catena-Poly[[(2,2'-bipyridine)copper(II)]-μ-5-tert-butyl-isophthalato].

Project description:In the crystal structure of the title polymeric compound, [Cu(C(12)H(12)O(4))(C(10)H(8)N(2))](n), the asymmetric unit consists of one Cu(II) ion, one 5-tert-butyl-isophthalate (tbip) and one 2,2'-bipyridine (bpy) ligand. The copper(II) ion is four-coordin-ated by two N atoms from bipy and two O atoms from two tbip ligands, leading to a distorted tetrahedral coordination. Each tbip ligand adopts a bis-monodentate coordination mode to connect two symmetry-related copper(II) ions, so forming a zigzag polymer chain parallel to [001]. The tert-butyl methyl groups are disordered over two positions with occupancies of 0.506 (6)/0.494 (6).

catena-Poly[[tripyridine-nickel(II)]-μ-5-bromo-isophthalato].

Project description:The title compound, [Ni(C(8)H(3)BrO(4))(C(5)H(5)N)(3)], is the first structurally characterized complex with a transition metal coordinated by a 5-bromo-isophthalate anion. The Ni(II) ion is coordinated by three O atoms from the carboxyl-ate groups and three N atoms from three pyridine ligands in a distorted octa-hedral coordination geometry. The 5-bromo-isophthalate anion is planar within 0.057 (2) Å. The two carboxyl-ate groups of the ligand coordinate the Ni(II) ions in a chelating and monodentate mode, linking the metal atoms into infinite chains along the [010] direction. These chains are stacked together via strong π-π inter-actions between the pyridine rings [centroid-centroid distance 3.601 (4) Å], forming a three-dimensional motif.

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

Project description:In the title compound, [Cu(C(14)H(8)O(5))(C(12)H(12)N(2))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. Two N atoms of the chelating 5,5'-dimethyl-2,2'-bipyridine (dbp) ligand and two O atoms of two different 2,2'-oxydibenzoic (odb) ligands occupy the basal plane while the water O atom completes the square-pyramidal geometry at the apical site. The non-water N(2)O(2) donor atoms are nearly coplanar, with a mean deviation from the least-squares plane of 0.0518 (11) Å and the Cu atom is displaced by 0.1507 (11) Å from this plane towards the apical water O atom. Further coordination via the 2,2'-oxydibenzoate anions forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure.

Project description:In the crystal structure of the title compound, [Cu(C(2)H(3)O(3))Cl(H(2)O)](n), the Cu(II) ion is five-coordinate in a distorted square-pyramidal geometry.

These chains are connected by O-H⋯O and O-H⋯Cl hydrogen bonds, forming an infinite three-dimensional polymeric network.
