Abstract
An unusually low V(H-H) stretching mode has been detected in the Raman spectrum of the molecular dihydrogen complex, [Ru(C5H5)(Ph(2)PCH(2)PP h(2))(eta(2)-H-2)]BF4, at 2082 cm(-1) which shifts to 1530 cm(-1) upon eta(2)-H-2 to eta(2)-D-2 substitution. Other isotope-sensitive modes associated with the triatomic RuH2 moiety are also detected at 1358, 6 79, 486,and 397 cm(-1), which are assigned to nu(as)(RuH2), nu(s)(RuH2 ), delta(RuH2) and delta(RuH2) modes, respectively.
