Catena-Poly[[bis-(?-5-bromo-pyridine-3-carboxyl-ato-?O:O')dicopper(II)]-bis-(?-5-bromo-pyridine-3-carboxyl-ato)-?O,O':N;?N:O,O'].

ABSTRACT: The title compound [Cu(2)(C(6)H(3)BrNO(2))(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxyl-ates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxyl-ates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitro-gen donor and extends two 5-bromo-pyridine-3-carboxyl-ate groups to bridge to adjacent binuclear sites in the bc plane. Each cage is linked to four adjacent cages in the plane. The intra-dimer Cu?Cu distance is 2.6465?(5)?Å. The remaining 5-bromo-pyridine-3-carboxyl-ate groups project into the inter-lamellar domain and inter-digitate in pairs from each neighboring layer.

Project description:In the title complex, [Ca(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), the Ca(II) ion is eight-coordinated by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands, two of which are bidentate chelate and two bridging, and two water mol-ecules in a distorted square-anti-prismatic geometry. The bridging groups form a polymeric chain substructure extending along the c axis, the chains being connected by coordinated-water O-H?N and O-H?O(carboxyl-ate) hydrogen bonds into a three-dimensional framework structure.

Tetra-kis(1,10-phenanthroline)bis-(?-pyridine-2,6-dicarboxyl-ato)(pyridine-2,6-di-carboxyl-ato)dicopper(II)terbium(III) nitrate tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Cu(2)Tb(C(7)H(3)NO(4))(3)(C(12)H(8)N(2))(4)]NO(3)·4H(2)O, consists of one-half of the C(2)-symmetric trinuclear coordination cation, one-half of the C(2)-symmetric nitrate anion and two water mol-ecules. In the coordination cation, the Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from a bridging-chelating carboxyl-ate group of the pyridine-2,6-dicarboxyl-ate anion, completing a distorted N(4)O(2) octa-hedral coordination environment. The Tb(III) atom, located on a twofold rotation axis, is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate anions forming an N(3)O(6) donor set. The intra-molecular Cu?Tb distance of 5.0592?(11)?Å indicates weak inter-actions between the Cu(II) and Tb(III) atoms. The coordination cations, nitrate anions and water mol-ecules are connected via O-H?O hydrogen bonds into layers parallel to the (001) plane. Moreover, there are extensive ?-? stacking inter-actions [centroid-centroid distances = 4.332?(7) and 3.878?(5)?Å] between the phenanthroline ligands and between phenanthroline and pyridine-2,6-dicarboxyl-ate ligands.

Project description:The asymmetric unit of the title compound, [MnBr(2)(C(6)H(4)NO(2))(H(2)O)(2)](n), contains one monomeric unit of the neutral linear coordination polymer. The Mn(3+) ions are bridged by anionic pyridine-2-carboxyl-ate (pic) ligands, thereby forming a chain-like structure along the c axis, and are six-coordinated in a distorted octa-hedral environment by two O atoms of the two different carboxyl-ate groups, two O atoms of two water mol-ecules and two Br atoms. The complex displays inter-molecular O-H?Br, O-H?N, O-H?O, C-H?O and C-H?Br hydrogen bonding. There may also be inter-molecular ?-? inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.993?(8)?Å.

catena-Poly[lead(II)-bis-(?-2-amino-1,3-benzothia-zole-6-carboxyl-ato)].

Project description:The title complex, [Pb(C(8)H(5)N(2)O(2)S)(2)](n), consists of one Pb(II) ion located on a crystallographic twofold axis and two symmetry-related 2-amino-1,3-benzothia-zole-6-carboxyl-ate (ABTC) ligands. The central Pb(II) ion has a (4 + 2) coordination by four O atoms of the two ABTC ligands and two weaker Pb-S bonding inter-actions (Pb-S secondary bonds) from S atoms of other two neighbouring ABTC ligands. These bonds link the metal ions into zigzag chains along the c axis, which, in turn, aggregate through ?-? inter-actions [centroid-centroid distance = 3.7436?Å] between ABTC rings and N-H?O and N-H?N hydrogen bonds.

catena-Poly[zinc(II)-?-aqua-?O:O-bis-(?-quinoline-4-carboxyl-ato-?O:O')].

Project description:The asymmetric unit of the title complex, [Zn(C(10)H(6)NO(2))(2)(H(2)O)](n), consists of one quinoline-4-carboxyl-ate anion, half of a Zn(2+) cation and half of a coordinated water mol-ecule. The cation and the water O atom have crystallographically imposed inversion and twofold rotation symmetry, respectively. The metal centre displays an elongated ZnO(6) octa-hedral coordination geometry provided by the O atoms of four anions at the equatorial plane and two axial water mol-ecules. Each anion and water mol-ecule act as bridges between Zn(II) cations, forming a polymeric chain parallel to [001]. The chains are further linked into a three-dimensional framework through O-H?N hydrogen bonds.

catena-Poly[cobalt(II)-bis-(?-3,7-dichloro-quinoline-8-carboxyl-ato-?N,O:O')].

Project description:In the crystal structure of the title compound, [Co(C(10)H(4)Cl(2)NO(2))(2)](n), the Co(II) cation lies on a twofold rotation axis. Each cation is N,O-chelated by the carboxyl-ate anions of two 3,7-dichloro-quinoline-8-carboxyl-ate ligands. The second carboxyl-ate O atom of each ligand coordinates to the Co(II) cation of an adjacent mol-ecule, linking the cations into a linear chain. Strong inter-chain ?-? stacking inter-actions are observed in the crystal structure (perpendicular distance 3.42?Å, centroid-to-centroid distance 3.874?Å).
