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.
