(η2-L)PtMe2 {L = [2.1.1]-(2,6)-pyridinophane} is protonated at Pt to give (η3-L)PtHMe2+, where three pyridine ligands of the macrocycle L bind to Pt in a facial manner. This cation eliminates methane at a rate convenient for trapping of the T-shaped, 14-valence electron (η2-L)PtMe+ (based on DFT geometry optimization) by ethane, propane, n-butane, cyclopentane and cyclohexane to give (η3-L)Pt(olefin)H+ and CH4. The crystal structure of (η3-L)Pt(cyclohexene)H+ as its BAr4F- salt is reported.
