Poly[aqua-{?(3)-5-[(pyridin-2-ylmeth-yl)amino]-isophthalato-?N,N':O,O:O}cobalt(II)].

ABSTRACT: In the title polymer, {[Co(C(14)H(10)N(2)O(4))(H(2)O)]·3.5H(2)O}(n), the Co(2+) ion is coordinated by three carboxyl-ate O atoms from two 5-[(pyridin-2-ylmeth-yl)amino]-isophthalate anions, two N atoms from a (pyridin-2-ylmeth-yl)amino group and an O atom from a water mol-ecule, furnishing a distorted CoO(4)N(2) octa-hedral geometry. Each anion acts as a ?(3)-bridge, linking cobalt ions into a two-dimensional layer parallel to (100). The asymmetric unit also contains three and a half solvent water mol-ecules, which could not be modeled. Therefore, the diffraction contribution of the solvent water mol-ecules was removed by the subroutine SQUEEZE in PLATON [Spek (2009). Acta Cryst. D65, 148-155]. The crystal structure is stabilized by O-H?O hydrogen bonds in which the coordinated water mol-ecule acts as donor and the carboxyl-ate O atoms as acceptors.

Project description:In the crystal structure of the title compound, [Co(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)](n), there are two symmetry-independent one-dimensional coordination polymers, which are approximately related by noncrystallographic inversion symmetry. Each zigzag chain is constructed from one Co(II) ion, one O-monodentate 5-nitro-isophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water mol-ecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN(2)O(4) octa-hedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-H⋯O hydrogen bonds arising from the water mol-ecules complete the structure.

Poly[di-aqua-[μ-1,4-bis-(pyridin-4-ylmeth-yl)pip-era-zine][μ-4-(carboxyl-atoeth-yl)benzoato]nickel(II)].

Project description:The title compound, [Ni(C10H8O4)(C16H20N4)(H2O)2]n, contains NiII cations octa-hedrally surrounded within an [O4N2] coordination set. The cations are linked by 4-(carb-oxy-eth-yl)benzoate (ceb) and 1,4-bis-(pyridin-4-ylmeth-yl)piperazine (bpmp) ligands into tri-periodic diamondoid (dia) networks. The fivefold inter-penetrated dia networks are held into the crystal structure by means of O-H⋯O hydrogen bonding between bound water mol-ecules and unligated carboxyl-ate O atoms of the ceb ligands.

Tetra-aqua-bis-[3-(pyridin-4-yl)benzoato-?N]cobalt(II).

Project description:In the title compound, [Co(C(12)H(8)NO(2))(2)(H(2)O)(4)], the Co atom lies on a twofold rotation axis and has an N(2)O(4) octa-hedral coordination environment formed by four O atoms of water mol-ecules in the equatorial plane and two apical N atoms of pyridine groups. An intricate three-dimensional supra-molecular network is formed by multiple O-H?O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate groups.

Project description:In the title compound, {[Co(C10H8O6)(C16H20N4)(H2O)2]·5H2O} n , octa-hedrally coordinated Co(II) ions on crystallographic inversion centres are bound by trans O atoms belonging to two hydro-quinone-O,O'-di-acetate (hqda) anions {systematic name: 2,2'-[(1,4-phenyl-ene)bis-(-oxy)]di-acetate}, two trans-pyridine N-donor atoms from two bis-(pyridin-4-ylmeth-yl)piperazine (4-bpmp) ligands, and two trans aqua ligands. The exobidentate hqda and 4-bpmp ligands form [Co(hqda)(4-bpmp)(H2O)2] n coordination polymer layers parallel to (110) that are anchored into the full crystal structure by O-H?O hydrogen bonding between aqua ligands and ligated hqda O atoms. Disordered water mol-ecules of crystallization occupy incipient channels along [100]. However, these could not modeled reliably and so they were treated with SQUEEZE in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]; the crystal data take the presence of these mol-ecules into account. The crystal under investigation was twinned by non-merohedry, the twin fraction of the components being 53.3% and 46.7%. Only data from the major twin component were used in the refinement.
