Vibrational assignments of the vinyl and vinylidene groups in 3(CO)10(μ-H)(μ-η2-CH=CH2)> (1) and 3(CO)9(μ-H)2(μ3-η2-C=CH2)> (3) respectively have been made on the basis of normal co-ordinate analyses of the Os3(C2Hn) (n=2 or 3) fragments and <2H> substitution. ?-Co-ordination caused the lowering of the principal ν(C=C) vibration to 1311 and 1331 cm-1 in (1) and (3) respectively.The vinyl group frequencies could largely be transferred to assign partially the spectrum of another vinyl complex 2(CO)3(η5-C5H5)2(μ-η2-CH=CH2)>BF4 (2) with the same co-ordination mode.The vinylidene frequencies in (3) were quite distinct from those of another complex, 2(CO)3(η5-C5H5)2(μ-C=CH2)> (4) which has a different co-ordination mode; a band at 1586 cm-1 in (4) is assigned as consisting largely of the ν(C=C) mode.Analysis was also made of the Os(μ-H) group in (1) and showed strong mixing between the symmetric ν(Os-H) and out-of-plane bend giving rise to the i.r. active vibrations at 1285 and 710 cm-1; the asymmetric ν(Os-H) stretch occurs at 1394 cm-1.
