title: A ruthenium(II)-porphyrin-carbene complex with a weakly bonded methanol ligand.
abstract: The title diphenylcarbene porphyrin complex (diphenylcarbenyl-kappaC)(methanol-kappaO)(5,10,15,20-tetra-p-tolylporphyrinato-kappa(4)N)ruthenium(II) methanol solvate, [Ru(C(13)H(10))(C(48)H(36)N(4))(CH(4)O)].CH(4)O, has a six-coordinate Ru atom with a methanol molecule as the second axial ligand. The carbene fragment is slightly distorted from an ideal sp(2) configuration, with a C(phenyl)-C(carbene)-C(phenyl) angle of 112.2 (3) degrees. The Ru-C bond length of 1.845 (3) A is comparable with other carbene complexes. The two phenyl rings of the carbene ligand are perpendicular to the carbene plane. Methanol solvate molecules link the methanol ligands of adjacent porphyrin complexes via hydrogen bonds.
