Аннотация

The preparation of a cobalt(II) chloride complex with a N-donor ligand 1-benzyl-5-methyl-1 H -imidazole of formula [CoCl2(1-benzyl-5-methyl-1 H -imidazole)2] is described. The isolated complex was characterized by UV, IR spectroscopy and crystallographic studies. Single crystal X-ray diffraction analysis of the complex reveals its monomeric tetra-coordinated nature. The coordination polyhedron around the cobalt center can be described as a quasi-regular tetrahedron. The Co-N distances for this compound are 2.0111(17) Å and 2.0118(17) Å, while the Co-Cl distances are 2.2582(7) Å and 2.2549(7) Å. The crystal packing can be described as layers parallel to (101) plane alternating along the b axis, and it is stabilized by p-p stacking between the imidazole and phenyl rings. The shortest centroid-centroid distance is 3.6002(14) Å.
