The crystal structure of [(bq)IrH(H2O)(PPh3)2]SbF6 (2, bq = 7,8-benzoquinolato) shows that benzoquinoline cyclometalates under conditions which give only a C-H?M bridged system with 8-methylquinoline. 2, a rare example of an organometallic aqua hydride complex, crystallizes in space group P21/c with a = 13.330 (4) ?, b = 18.131 (5) ?, c = 21.777 (7) ?, β = 98.86 (3)°, and Z = 4. The possible intermediacy of η2-arene species is considered and rejected, and a transition state (7) for the C-H oxidative addition is proposed.
Some Molecular Hydrogen Complexes of Iridium

, p. 4032 - 4037 (2007/10/02)
The new molecular hydrogen complexes + (bq = 7,8-benzoquinolinate, L = PPh3 or PCy3) and + are described.A 1H NMR T1 criterion is proposed for detecting such complexes.Deprotonation of the coordinated H2 is described.The mechanism of hydrogenolysis of d0 alkyls is discussed and a dihydrogen complex proposed as intermediate.
