(5,10,15,20-Tetraphenylporphyrinato-κ4 N)(2,2,2-trifluoro-1-phenylethylidene-κC 1)ruthenium(II): a stable fluorinated alkylidene complex of a ruthenium(II) porphyrin

چکیده
In the title compound, [Ru(C(44)H(28)N(4))(C(8)H(5)F(3))], the fluorin-ated alkyl-idene 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 C(20)N(4) porphyrin core. The Ru=C bond is tilted slightly from the normal to the C(20)N(4) least-squares plane due to steric repulsion between the porphyrinate ligand and the bulky trifluoro-methyl group. The Ru=C bond length of 1.838 (2) Å is comparable with those in bis-(subsituted phen-yl)carbene analogs.
