sulfur atom and metal centers. The crystal structure of 4contains two independent dinuclear molecules that interconvert formally by exchange of tBuO and chelating OSOMe} ligands between terminal and bridging modes and feature normal Zr−S bonds. NMR data for 4 and 12 are consistent with dinuclear C1-symmetric structures in toluene solution, while dibenzyl complex 8 has a mononuclear structure. Variable-temperature
