Another example of the conformation‐determining attractive interaction between gold(I) centers is presented, based on changes in the conformation of the butadiene skelton. The s ‐ trans ground state geometry of 2,3‐bis(diphenylphosphino)‐1,3‐butadiene ( 2 ) is abandoned in the gold complex 3 , and the two gold atoms are brought into contact at a distance of 3.023(1) Å. The conformational change of the Ligand also occurrs at a single metal atom, where the bisphosphine acts as a difunctional chelating ligand, as demonstrated in the rhodium complex 4 .
