Influence of the bridging tetrazole containing ligands on magnetic properties of 3d metal complexes.
trans-DichloridotetrakisÂ[1-(2-hydroxyÂethyl)-1H-tetrazole-κN 4]cobalt(II)
The title cobalt(II) complex, [CoCl2(C3H6N4O)4], was obtained from metallic cobalt by direct synthesis. There are two Co atoms in the asymmetric unit, each lying on an inversion centre and adopting a distorted octaÂhedral coordination. Classical and non-classical hydrogen bonds are responsible for formation of a three-dimensional polymeric network in the crystal
catena-Poly[cobalt(II)-di-μ-chlorido-κ4 Cl:Cl-μ-1,5-dimethyl-1H-tetraÂzole-κ2 N 3:N 4]: an X-ray powder investigation
The asymmetric unit of the title compound, [CoCl2(C3H6N4)]n, contains two Co atoms, both lying on inversion centres, two Cl atoms and one 1,5-dimethylÂtetraÂzole ligand. The coordination polyhedra of both Co atoms adopt flattened octaÂhedral geometry, with two N atoms from two ligands in axial positions and four Cl atoms in equatorial sites. Neighbouring Co atoms are linked together via two bridging Cl atoms and one tetraÂzole ring to form polymeric chains running along the a axis
