Abstract
A 16-electron dicationic dihydrogen complex [Ru(η2-H···H)(PP)2][OTf]2 [4; PP = (C6H5CH2)2PCH2CH2P(CH2C6H5)2] has been prepared and characterized by protonating the precursor hydride complex [Ru(H)(PP)2)][OTf] (2) using HOTf. The hydride and dihydrogen complexes are stabilized via agostic interaction of the ortho C−H fragment of the phenyl ring on the benzyl group. The intact nature of the H−H bond in this derivative was established from the short spin−lattice relaxation time and the observation of a substantial J(H,D) of 22.0 Hz for the HD isotopomer. The H−H bond distance calculated from J(H,D) is 1.05 Å, which falls under the category of elongated dihydrogen ligands.
