title: A five-coordinate ruthenium(II)-porphyrin-carbene complex: [bis(3-trifluoromethylphenyl)methylene-kappaC](5,10,15,20-tetra-p-tolylporphyrinato-kappa4N)ruthenium(II).
abstract: The stable title trifluoromethyl-substituted carbenyl metalloporphyrin, [Ru(C(15)H(8)F(6))(C(48)H(36)N(4))], has a five-coordinate Ru atom which is displaced from the porphyrin N(4) plane towards the axial carbene ligand by 0.230 (3) A. The Ru--C(carbene) bond coincides with a crystallographic twofold axis and its length of 1.841 (6) A is notably shorter than the value of 1.868 (3) A in the pyridine adduct.
