Abstract The photochemical synthesis of the title complex from 1,3‐butadiene and dodecacarbonyltriosmium is described. The 1 H‐NMR. and H‐coupled 13 C‐NMR. spectra are analyzed completely and the H, H‐ and C,H‐coupling constants compared with the data of the corresponding Fe‐ and Ru‐complexes. One‐bond 13 C, 13 C‐coupling constants are reported for a series of complexed 1,3‐dienes. All data are consistent with an increasing distortion from planarity of the C,H‐skeleton at the terminal diene C‐atoms in the sequence Fe → Ru → Os.
