Dichlorido(2-chloro-9-mesityl-1,10-phenanthroline-²N,N')cobalt(II) dichloromethane hemisolvate

Y. Yang, P. Yang, C. Zhang and B. Wu

Abstract: The title compound, [CoCl₂(C₂₁H₁₇ClN₂)]·0.5CH₂Cl₂, crystallizes from dichloromethane as a 2:1 solvate [CoCl₂L]₂·CH₂Cl₂ (L is 2-chloro-9-mesityl-1,10-phenanthroline). There are two independent CoCl₂L molecules in the asymmetric unit and both molecules have similar conformations. They are connected by a weak C-H interaction involving the mesityl ring. The cobalt center is four-coordinated by the two N-atom donors of the bidentate ligand and two chloride ions in a distorted tetrahedral geometry. The packing of the molecules is stabilized by weak slipped - stacking interactions between symmetry-related phenanthroline groups.
