Solid-state structures of a 1-CHCH2 and b 1-CCH3 with 50% probability thermal ellipsoids. For clarity, only the hydrogen atoms at vinyl and carbyne ligands are shown, and the phenyl groups are drawn as lines. Selected bond distances (Å) and angles (deg): for 1-CHCH2, Fe–Mo 2.5313(8), Mo–P 2.4541(11), Mo–S 2.3397(11), Mo–C1 2.107(4), Mo–C2 2.301(5), C1–C2 1.404(7), Fe–S 2.2193(13), Fe–C1 1.962(5), Fe–S–Mo, 67.39(4), Fe–C1–Mo, 76.85(16); for 1-CCH3, Fe–Mo 2.5167(5), Mo–P 2.4032(8), Mo–S 2.3424(8), Mo–C1 1.905(3), C1–C2 1.470(5), Fe–S 2.2512(8), Fe–C1 1.901(3), Fe–S–Mo, 66.41(2), Fe–C1–Mo, 82.79(13). c Eyring plot of the conversion 1-CHCH2 → 1-CCH3 in d8-toluene with 30 ppm of H2O.
