Bis-H2 complexes

These peaks coalesce at 200 K, and Morris [8] calculates the AGl at this temperature to be 8.4 kcal moH. Chaudret s bis-H2 complex, RuH2(H2)2(PCy3)2, is also... 

The cis effect has also been observed experimentally and calculationally in several other Ru complexes, including bis(H2) complexes. The extremely fluxional RuH2(H2)2(PCy3)2, which has alow H2 rotational barrier (1.1 kcal/mol see Chapter... 

The crystal structure of a bis-(H2) complex has now been determined, RuH2(H2)2(P Pr3)2 showed disorder but electron density in the difference Fourier...
