Abstract: The title compound, [N₃P₃(C₅H₇N₂)₄(C₆H₅)₂]CoCl₂ or [CoCl₂(C₃₂H₃₈N₁₁P₃)], possesses a five-coordinated Co^II atom in an approximately trigonal-bipyramidal geometry. The N₃Cl₂ donor set of the metal environment comprises two non-geminal pyrazolyl N atoms, one cyclotriphosphazene N atom, and two Cl^- ions. The coordination environment and bonding features of the compound are critically compared with related metal complexes of cyclotriphosphazene ligands.
