The title compound, CoL2Cl2 [L = (2,4-dichloro-phenol-methylene-1H- -benzimidazole)], has been synthesized and structurally characterized by elemental analysis, IR and X-ray. The coordination geometry of cobalt(II) may be represented by slightly distorted tetrahedron with the CoN2Cl2 chromophore. In the solid state, the title compound forms infinite one-dimensional chains in the [101] direction through hydrogen bonds and potentially weak intermolecular interactions. The IR data agree with the crystal structure. The thermal gravimetry (TG) data indicate that there are two decomposition steps. The final product of thermal decomposition is Co2O3. The magnetic properties of the title compound are also reported and discussed.
