Crystallographic and theoretical studies of (η5-C5Me5)Ru(2,4-dimethyl-η5-pentadienyl) and [(η5-C5Me5)Rh(2,4-dimethyl-η5-pentadienyl)][BF4]

Synthesis, characterization, and crystal structures of Cp*Ru(2,4-dimethyl-η5-pentadienyl) and Cp*Rh(2,4-dimethyl-η5-pentadienyl)+, where Cp* = pentamethyl-cyclopentadienyl, are reported and the geometry of the complexes analyzed based on the density functional theory studies of their simplified analog Cp*Ru(η5-pentadienyl).
