Abstract: The title dimeric zirconium complex, [Zr3(C20H 24)2S2]·C7H8, was obtained from the reaction of (ebthi)Zr(η2-Me3Si-C2-SiMe3) [ebthi is rac-1,2-bis(η5-4,5,6,7-tetrahydroinden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile C N-ada. Each ZrIV atom is coordinated by the sterically hindered ebthi ligand and two μ-sulfide ligands in a strongly distorted tetrahedral geometry. The [ZrS]2 unit is almost planar (mean deviation from the best plane of the four atoms = 0.025Å). A -CH2-CH2- group in one ebthi ligand was disordered over two sites, with refined occupancy factors of 0.551(6) and 0.449(6). The asymmetric unit also contains a toluene solvent molecule.
