Poly[(?(2)-quinoline-3-carboxyl-ato-?N:O)(?(2)-quinoline-3-carboxyl-ato-?N:O,O')cadmium].

ABSTRACT: In the title compound, [Cd(C(10)H(6)NO(2))(2)](n), the Cd(II) atom is coordinated by three O atoms and two N atoms from four quinoline-3-carboxyl-ate (L(-)) ligands, leading to a distorted trigonal-bipyramidal geometry. The L(-) ligands link the Cd(II) atoms into a plane parallel to (100), with one ligand being tridentate, coordinating via the N atom and chelating a second Cd atom, and the other being bidentate, bridging two Cd atoms via the N and one O atom.. This two-dimensional network extends into a double-layer network by ?-? inter-actions, with centroid-centroid distances of 3.680?(2) and 3.752?(2)?Å. Another type of ?-? inter-action between pyridine rings [centroid-centroid distance = 3.527?(2)?Å] leads to a three-dimensional supra-molecular architecture.

Project description:In the title layered coordination polymer, {[Cd(C(17)H(18)F(2)N(3)O(3))(C(8)H(4)O(4))]·3H(2)O}(n), the Cd(II) atom exhibits a very distorted CdO(6) octa-hedral geometry defined by one O(3),O(4)-bidentate 1-ethyl-6,8-difluoro-7-(3-methyl-piperazin-1-yl)-4-oxo-1,4-dihydro-quinoline-3-carboxyl-ate (lome) ligand, one O,O'-bidentate benzene-1,4-dicarboxyl-ate (bdc) dianion and two O-monodentate bdc dianions. Both the bdc species in the asymmetric unit are completed by crystallographic inversion symmetry. The bridging bdc dianions link the cadmium nodes into a recta-ngular grid lying parallel to (01). A network of N-H?O and O-H?O hydrogen bonds helps to establish the packing.

Project description:The neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (?-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monodentate, two bidentate. Weak inter-molecular ?-? inter-actions [centroid-centroid distance = 3.712?(3)?Å] help to establish the packing of the structure.

Poly[bis-(?-hemihydrogen 2-phenyl-quinoline-4-carboxyl-ato-?N,O)silver(I)].

Project description:In the title compound, [Ag(C(16)H(10.5)NO(2))(2)], the Ag(I) cation (site symmetry 2) is coordinated by two N atoms in a near-linear AgN(2) arrangement. Two carboxyl-ate O atoms from two additional 2-phenyl-quinoline-4-carboxyl-ate ligands form long Ag-O bonds [2.6585?(17)?Å], resulting in a distorted square-planar arrangement. The bridging ligands result in infinite corrugated sheets propagating in (010). An O-H?O hydrogen bond, disordered about a twofold axis, completes the structure.

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[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

Poly[di-μ(2)-azido-μ(3)-pyrazine-2-carboxyl-ato-cadmium(II)].

Project description:The title compound, [Cd(C(5)H(3)N(2)O(2))(N(3))](n), has been pre-pared by the reaction of pyrazine-2-carboxylic acid, cadmium(II) nitrate and sodium azide. In the structure, the Cd(II) atom is six-coordinated by two azide anions and three pyrazine-2-carboxyl-ate ligands. Each pyrazine-2-carboxyl-ate ligand bridges three Cd(II) atoms, whereas the azide ligand bridges two Cd(II) atoms, resulting in the formation of a two-dimensional metal-organic polymer developing parallel to the (100) plane.
