A suitable antimony source for complexes with substituent‐free Sb n ligands is the four‐membered ring ( t BuSb) 4 , which reacts with [{C 5 H 5 (CO) 3 Mo} 2 ] to yield the tetrahedranes 1 and 2 , and with [{C 5 Me 5 (CO) 3 Mo} 2 ] to give 3 . Compounds 2 and 3 are the first complexes to contain the cyclo ‐Sb 3 ligand. In the crystal they are linked through close SbSb interactions.
