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.

The bridging carboxyl-ate O atoms [Sr-O = 2.498?(3) and 2.495?(3)?Å] link Sr(II) atoms, forming a chain substructure extending along the c axis. The chains are linked by O-H?N and O-H?O hydrogen bonds, giving a three-dimensional framework structure.

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.

Poly[di-?(2)-azido-?(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.

Weak inter-molecular ?-? inter-actions [centroid-centroid distance = 3.712?(3)?Å] help to establish the packing of the structure.

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.

Poly[bis-(ethanol)(?4-2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ato)cadmium].

Project description:In the title compound, [Cd(C8F4O4)(C2H5OH)2] n , the Cd(II) cation sits on an inversion centre and is coordinated by six O atoms from four tetra-fluoro-benzene-1,4-di-carboxyl-ate anions and two ethanol mol-ecules in a distorted octa-hedral geometry. The anionic ligand is also located on an inversion centre, and connects four Cd(II) cations, generating a two-dimensional polymeric layer parallel to the ab plane. Within the layer, the ethanol mol-ecule links F and O atoms of the nearest anionic ligands via O-H?O and O-H?F hydrogen bonds. The ethyl group of the ethanol mol-ecule is disordered over two positions with an occupancy ratio of 0.567?(10):0.433?(10).
