Abstract: The title dimeric zirconium complex, [Zr₂(C₂₀H₂₄)₂S₂]·C₇H₈, was obtained from the reaction of (ebthi)Zr(²-Me₃Si-C₂-SiMe₃) [ebthi is rac-1,2-bis(⁵-4,5,6,7-tetrahydroinden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile CN-ada. Each Zr^IV atom is coordinated by the sterically hindered ebthi ligand and two -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 = 0.025 Å). 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.
