Catena-Poly[[[di-aqua-cobalt(II)]-bis-{?-2-[3-(4-carboxyl-atophen-yl)pyridin-1-ium-1-yl]acetato}] dihydrate].

ABSTRACT: 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 ?-? stacking inter-actions [inter-planar and centroid-centroid distances of 3.658?(3)?Å and 3.653?(2)?Å, respectively].

Adjacent polyhedra share two O?O edges. The polymeric chains are linked into a three-dimensional network via O-H?O and O-H?N hydrogen bonds.

Project description:In the title complex, {[Cd(CH(3)COO)(2)(C(11)H(8)N(2)O)(H(2)O)]·2H(2)O}(n), the Cd(II) ion adopts an O(5)N(2) penta-gonal-bipyramidal coordination geometry with four acetate O atoms and one water O atom at the equatorial sites and two pyridine N atoms at the axial sites.

Bis(2,6-diamino-pyridin-1-ium) hexa-aqua-cobalt(II) disulfate dihydrate.

Project description:In the title compound, (C(5)H(8)N(3))(2)[Co(H(2)O)(6)](SO(4))(2)·2H(2)O, the complete complex cation is generated by crystallographic inversion symmetry, such that the Co(II) cation is octa-hedrally coordinated by six water mol-ecules. The organic cation is essentially planar, with a maximum deviation of 0.013?(1)?Å. In the crystal structure, the ions and mol-ecules are linked into a pseudo-layered three-dimensional supra-molecular network via O-H?O and N-H?O hydrogen bonds. Weak inter-molecular ?-? inter-actions further stabilize the crystal structure [centroid-centroid distance = 3.5231?(4)?Å].

Project description:In the title compound, [Cu(CH(3)CO(2))(2)(C(9)H(7)N(3))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. The N atoms of the two chelating symmetry-related 5-(pyridin-3-yl)pyrimidine ligands and the O atoms of the two monodentate acetate anions are nearly coplanar, with a mean deviation from the least-squares plane of 0.157?(2)?Å and the Cu(II) ion is displaced by 0.050?(3)?Å from this plane towards the apical water O atom. Bridging through the bis-monodentate 5-(pyridin-3-yl)pyrimidine ligand forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure parallel to (100). The crystal studied was an inversion twin with a 0.57?(3):0.43?(3) domain ratio.
