[?-6,9-Bis(carboxylatomethyl)-3,12-bis(car-boxymethyl)-3,6,9,12-tetraaza-tetradecanedioato]bis-[aqua-cobalt(II)] tetra-hydrate.

ABSTRACT: The binuclear title complex, [Co(2)(C(18)H(26)N(4)O(12))(H(2)O)(2)]·4H(2)O, lies about a centre of inversion, the Co(II) atom being coordinated in a distorted octa-hedral arrangement defined by one water mol-ecule and N(2)O(3) donors derived from one end of a 6,9-bis(carboxylatomethyl)-3,12-bis(car-boxy-methyl)-3,6,9,12-tetraaza-tetradecanedioate (H(2)TTHA(4-)) tetra-anion. In the crystal, numerous O-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Project description:The asymmetric unit of the title compound, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(5)O(3))(2)·4H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 3-hy-droxy-benzoate counter-anion and two uncoordinated water mol-ecules.

In the anion, the carboxyl-ate group is twisted from the attached benzene ring at 8.84?(17)°. In the crystal, a three-dimensional hydrogen-bonding network, formed by classical O-H?O and N-H?O hydrogen bonds, consolidates the crystal packing, which exhibits ?-? inter-actions between the benzene and pyridine rings, with centroid-centroid distances of 3.458?(1) and 3.606?(1)?Å, respectively.

Tetra-aqua-bis(nicotinamide-?N)cobalt(II) bis-(2-fluoro-benzoate).

Project description:The title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(4)FO(2))(2), contains one Co(II) atom (site symmetry ), two monodentate nicotin-amide (NA) ligands, four coordinated water mol-ecules and two 2-fluoro-benzoate (FB) anions. The four O atoms in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 29.8?(3)°, while the pyridine and benzene rings are oriented at a dihedral angle of 7.97?(12)°. In the crystal structure, mol-ecules are linked by O-H?O, N-H?O and N-H?F hydrogen bonds, forming an infinite three-dimensional network. ?-?

Tetra-aqua-bis-(piperazin-1-ium)cobalt(II) bis-(sulfate) dihydrate.

Project description:In the centrosymmetric title compound, [Co(C4H11N2)2(H2O)4](SO4)2·2H2O, the Co(II) atom is coordinated in a distorted octa-hedral geometry by four water O atoms and two piperazinium N atoms. These four water O atoms define an equatorial plane with a maximum deviation of 0.0384 (1) Å while the two piperazinium N atoms complete the octa-hedron in the axial positions. Neighboring complex mol-ecules and sulfate anions are connected through an extensive network of N-H⋯O and O-H⋯O hydrogen bonds, which link the different chemical species into layers in the ab plane. Additional Owater-H⋯O hydrogen bonds involving the non-coordinating water mol-ecules and C-H⋯O inter-actions connect these layers into a three-dimensional supra-molecular structure.
