Catena-Poly[[[diaqua-sodium]-di-?-aqua] 2-(2-pyrid-yl)quinoline-4-carboxyl-ate].

ABSTRACT: In the title compound, [Na(H(2)O)(4)](C(15)H(9)N(2)O(2)), the Na(+) ion is coordinated by six water mol-ecules in an octa-hedral geometry. The NaO(6) octa-hedra are connected by sharing edges, forming a cationic chain along the b-axis direction. O-H?O and O-H?N hydrogen bonds link the chains and the 2-(2-pyrid-yl)quinoline-4-carboxyl-ate anions into a two-dimensional network parallel to (100).

Project description:The title compound, [Sr(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), contains an eight-coordinate Sr(II) ion displaying a distorted square-anti-prismatic geometry, two quinoline-3-carboxyl-ate ligands and two terminal water mol-ecules. The Sr(II) atom is surrounded by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands and two O atoms from two coordinated water mol-ecules. 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.

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.

Project description:In the title polymeric coordination compound, {[Co(C14H10NO4)2(H2O)2]·2H2O} n , the Co(II) ion resides on an inversion center and exhibits a distorted o-cta-hedral coordination geometry defined by four O atoms from two pairs of equivalent monodentate carboxyl-ate groups from 2-[3-(4-carboxyl-atophen-yl)pyridin-1-ium-1-yl]acetate ligands and by two O atoms from two equivalent coordinating water mol-ecules. The zwitterionic di-carboxyl-ate ligands serve as bridges with two monodentate carboxyl-ate and the metal ions are linked by double bridges, forming polymeric chains running along [01-1]. The chains are further stabilized and associated into layers parallel to (011) through intra- and inter-chain hydrogen bonding and π-π stacking inter-actions [inter-planar and centroid-centroid distances of 3.658 (3) Å and 3.653 (2) Å, respectively].
