(5,10,15,20-Tetraphenylporphyrinato-⁴N)(2,2,2-trifluoro-1-phenylethylidene-C¹)ruthenium(II): a stable fluorinated alkylidene complex of a ruthenium(II) porphyrin

Abstract: In the title compound, [Ru(C₄₄H₂₈N₄)(C₈H₅F₃)], the fluorinated alkylidene group is bound to a five-coordinate Ru atom, which is located toward the carbene C atom, 0.3301 (5)Å from the least-squares plane of the C₂₀N₄ porphyrin core. The Ru=C bond is tilted slightly from the normal to the C₂₀N₄ least-squares plane due to steric repulsion between the porphyrinate ligand and the bulky trifluoromethyl group. The Ru=C bond length of 1.838 (2) Å is comparable with those in bis(subsituted phenyl)carbene analogs.
