Abstract
The two sulfide-bridged dirhenium complexes bis(mu-4-methoxyphenylsulfido-S )bis(tetracarbonylrhenium), [Re-2(C7H7OS)(2)(CO)(8)], and bis(mu-naphthylsu lfido-S)bis[tricarbonyl(dicyclohexylphosphane)rhenium], [Re-2(C12H23P)(2)(C 10H7S)(2)(CO)(6)], show different geometries of the common Re2S2 core. The 4-methoxyphenyl derivative has crystallographic (1) over bar symmetry and t he naphthyl derivative has C-2 symmetry. This results from intramolecular r epulsion due to different substitution patterns at the Re and S atoms.
