Catena-Poly[[(pyridine-?N)copper(II)]-?(3)-pyridine-2,6-dicarboxylato-?O:O,N,O:O].

ABSTRACT: In the title compound, [Cu(C(7)H(3)NO(4))(C(5)H(5)N)](n), the Cu(II) atom is in a slightly distorted octa-hedral coordination environment. Each Cu(II) atom is bound to two N atoms and one O atom of the pyridine-dicarboxyl-ate (PDA) ligand in a tridentate manner, one N atom of the pyridine mol-ecule and two bridging carboxyl-ate O atoms of adjacent PDA ligands, leading to a linear one-dimensional chain running along the c axis. These chains are further assembled via weak C-H?O and ?-? inter-actions into a three-dimensional supra-molecular network structure. The centroid-centroid distance between the ?-? inter-acting pyridine rings is 3.9104?(13)?Å. The two N atoms are trans to each other with respect to Cu.

Project description:The two independent Ni(II) ions in the one-dimensional title complex, [Ni(2)(C(7)H(3)NO(4))(2)(C(12)H(8)N(4)S)(H(2)O)(2)](n) or [Ni(2)(pydc)(2)(bpt)(H(2)O)(2)](n) (H(2)pydc = pyridine-2,6-dicarboxylic acid and bpt = 2,5-di-4-pyrid-yl-1,3,4-thia-diazole), have different coordination environments. One Ni(II) ion is in a slightly-distorted octa-hedral coordination environment formed by three O atoms from two adjacent pydc ligands, two N atoms from bpt and pydc ligands, and one water mol-ecule, while the other Ni(II) ion is in distorted square-pyramidal geometry, coordinated by two O atoms from two carboxyl-ate groups and two N atoms from the pyridine rings of the pydc and bpt ligands in the basal plane, while a coordinated water mol-ecule occupies the apical site. In the crystal structure, the H atoms of both water mol-ecules are involved in inter-molecular hydrogen bonds with the O atoms of uncoordinated carboxyl-ate groups, which link chains into a three-dimensional network.

Project description:In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry. The bridging ligand results in an infinite chain. A network of O-H?O hydrogen bonds helps to establish the crystal structure.

catena-Poly[[(3-methyl-pyridine)-copper(I)]-?-cyanido-copper(I)-?-cyanido].

Project description:In the title complex, [Cu(2)(CN)(2)(C(6)H(7)N)](n), there are two copper atoms with different coordination environments. One Cu atom (Cu1) is linked to the two cyanide ligands, one N atom from a pyridine ring while the other (Cu2) is coordinated by the two cyanide ligands in a slightly distorted tetra-hedral geometry and linked to Cu1, forming a triangular coordination environment. The Cu atoms are bridged by bidentate cyanide ligands, forming an infinite Cu-CN chain. One cyanide ligand is equally disordered over two sets of sites, exchanging C and N atoms coordinated to both metal atoms. However, one cyanide group is not disordered and it coordinates to Cu1 via the N atom whereas its C-atom counterpart coordinates Cu2. The 3-methyl-pyridine (3MP) ligand coordinates through the N atom to Cu1 as a terminal ligand, which originates from decyanation of 3-pyridyl-acetonitrile under hydro-thermal conditions. Adjacent Cu-CN chains are inter-connected through Cu?Cu inter-actions [2.8364?(10)?Å], forming a three-dimensional framework.

catena-Poly[[(1,10-phenanthroline)copper(II)]-?-oxalato].

Project description:In the title coordination polymer, [Cu(C(2)O(4))(C(12)H(8)N(2))](n), the Cu(II) atom is six-coordinated by four O atoms from two oxalate ligands and two N atoms from one 1,10-phenanthroline (phen) ligand in a distorted octa-hedral coordination geometry. The oxalate anions act as bis-bidentate ligands, bridging the Cu-phen units in zigzag chains extending parallel to [100]. Inter-chain C-H?O hydrogen bonding and ?-? stacking inter-actions [centroid-centroid distance = 3.7439?(17)?Å] assemble neighboring chains, forming a three-dimensional supra-molecular network.

Project description:In the title compound, [Cu(C(10)H(8)O(6))(C(5)H(5)N)(2)(H(2)O)](n), the Cu atom is five-coordinated by two O atoms from two carboxyl-ate groups of two different 2,2'-(p-phenyl-enedi-oxy)diacetate ligands, two N atoms from two pyridine mol-ecules and one water O atom. The geometry is square-pyramidal with the water O atom occupying the apical position. The carboxyl-ate group bridges adjacent Cu atoms, forming an infinite zigzag chain extending parallel to [001]. The chains are linked into layers by O-H?O hydrogen bonds. The Cu and water O atoms lie on special positions of site symmetry 2.

catena-Poly[[[tetra-kis-(4-methyl-pyridine-κN)copper(II)]-μ-sulfato-κO:O'] 4.393-hydrate].

Project description:The structure of the title compound, {[Cu(SO(4))(C(6)H(7)N)(4)]·4.393H(2)O}(n), consists of Cu(2+) ions surrounded in a square-planar fashion by 4-methyl-pyridine ligands, forming two crystallographically independent Cu{H(3)C(C(5)H(4)N)}(4) units that are both located on crystallographic inversion centers. The Cu(4-methyl-pyridine)(4) units are, in turn, connected with each other via bridging sulfate anions, leading to the formation of infinite [Cu{H(3)C(C(5)H(4)N)}(4)SO(4)](n) zigzag chains along [001]. The completed coordination spheres of the Cu(2+) ions are slightly distorted octa-hedral. The axial Cu-O bonds are elongated [average length = 2.42 (4) Å] compared to the equatorial Cu-N bonds [average length = 2.043 (2) Å]. The inter-stitial space between the chains is filled with uncoordinated water mol-ecules that consolidate the structure through O-H⋯O hydrogen bonding. One of the five crystallographically independent solvent water mol-ecules is partially occupied with an occupancy factor of 0.396 (4). Due to hydrogen bonding between symmetry-equivalent water mol-ecules across inversion centers, several of the water H atoms are disordered in 1:1 ratios over mutually exclusive positions. The crystal under investigation was found to be non-merohedrally twinned in a 0.789 (1):0.211 (1) ratio by a 180° rotation around the reciprocal b axis.

Project description:The title compound, [Cu(3)(C(7)H(3)NO(4))(4)(C(2)H(8)N(2))(2)]·C(2)H(8)N(2)·4H(2)O, was obtained by the reaction of copper(II) acetate dihydrate with pyridine-2,6-dicarb-oxy-lic acid (H(2)dipic) and ethyl-enediamine (en) in an aqueous solution. All of the Cu(II) atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octa-hedral geometry with N(2)O(4) and N(4)O(2) environments for the outer and central Cu(II) atoms, respectively. Various inter-actions, including numerous O-H?O and C-H?O hydrogen bonds and C-O?? stacking of the pyridine and carboxyl-ate groups [O?centroid distances = 3.669?(2) and 3.668?(2)?Å] are observed in the crystal structure.
