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.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
