Di-aqua-dichlorido-bis-(pyridine-?N)cobalt(II).

ABSTRACT: The title mol-ecule, [CoCl2(C5H5N)2(H2O)2], has -1 symmetry with the Co(II) ion situated on an inversion centre. The cation has a distorted octa-hedral coordination environment and is surrounded by two N and two Cl atoms in the equatorial plane, while the coordinating water O atoms occupy the axial positions. The crystal exhibits nonmerohedral twinning with two domain states, the volume fractions of which were refined to 0.883?(2) and 0.117?(3). The crystal packing is stabilized by O-H?Cl hydrogen-bond inter-actions, forming two-dimensional networks lying parallel to (001). The crystal packing also features ?-? inter-actions between the pyridine rings, with centroid-centroid separations of 3.493?(3) and 3.545?(3)?Å.

Project description:In the title compound, [Co(2)(C(2)H(3)O(2))(4)(C(7)H(6)N(2))(4)(H(2)O)], the half-mol-ecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full mol-ecule.

The compound features intra-molecular O-H?O hydrogen bonds between the non-bridging acetate groups and the bridging water mol-ecule, and inter-molecular N-H?O hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the mol-ecular packing in the crystal structure.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38?Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87?(2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H?O, C-H?N, O-H?O and N-H?O hydrogen bonds.

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-cobalt(II) bis-(sulfate) dihydrate.

Project description:The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093?(17)?Å], but are significantly longer than in the isotypic Ni(II) compound (?d ? 0.04?Å). The cobalt cation reaches an overall bond-valence sum of 1.97 valence units. The S-O distances are nearly equal, ranging from 1.454?(4) to 1.470?(3)?Å [mean 1.465?(12)?Å]; however, the O-S-O angles vary clearly from 108.1?(2) to 110.2?(2)° [average bond angle 109.5?(9)°]. The non-coordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate tetrahedra and the [Co(H2O)6](2+) octa-hedron via O-H?O and N-H?O hydrogen bonds of weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel to (001).

The bis-(pyridine-2,6-dicarboxyl-ato)cobalt complex units are connected by Na(+) cations and bridging water mol-ecules into a three-dimensional coordination network. O-H?O hydrogen bonds are formed between the water mol-ecules and the carboxyl-ate O atoms.
