Bis(2-hydroxy-N'-isopropylidenebenzo-hydrazidato-κN',O)bis-(pyridine-κN)cobalt(II).

ABSTRACT: In the title complex, [Co(C(10)H(11)N(2)O(2))(2)(C(5)H(5)N)(2)], the Co(II) atom lies on a centre of symmetry and adopts a distorted cis-CoO(2)N(4) octa-hedral geometry. The two acetone salicyloylhydrazone ligands are deprotonated and act as N,O-bidentate monoanionic ligands, forming the equatorial plane, while the axial positions are occupied by two N atoms of two pyridine mol-ecules. The complex presents O-H⋯N and C-H⋯N intra-molecular hydrogen bonds. Inter-molecular C-H⋯N and C-H⋯O inter-actions are also present in the crystal.

Bis(3-acetyl-pyridine-κN)diaqua-bis-(seleno-cyanato-κN)cobalt(II).

Project description:In the crystal structure of the title compound, [Co(NCSe)(2)(C(7)H(7)NO)(2)(H(2)O)(2)], the Co(2+) cation is coordinated by two seleno-cyanate anions, two 3-acetyl-pyridine ligands and two water mol-ecules within a slightly distorted CoN(4)O(2) octa-hedron. The asymmetric unit consists of one Co(2+) cation, which is located on a center of inversion, as well as one seleno-cyanate anion, one 3-acetyl-pyridine ligand and one water mol-ecule in general positions. Whereas one of the water H atoms makes a classical O-H⋯O hydrogen bond, the other shows a O-H⋯Se inter-action.

Di-aqua-dichlorido-bis-(pyridine-κN)cobalt(II).

Project description: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 π-π 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(C(7)H(5)O(2))(2)(C(5)H(6)N(2))(2)], the Co(II) atom is hexa-coordinated by four O atoms from two benzoate anions, and two N atoms from two 2-amino-pyridine mol-ecules, resulting in a distorted octa-hedral geometry.

The crystal packing is stabilized by inter-molecular N-H⋯O hydrogen bonds, C-H⋯π, and π-π stacking inter-actions involving benzoate anions and 2-amino-pyridine mol-ecules.
