Di-μ-sulfido-bis-{[rac-1,2-bis-(η(5)-4,5,6,7-tetra-hydro-inden-1-yl)ethane]-zirconium(IV)} toluene monosolvate.

The title dimeric zirconium complex, [Zr(2)(C(20)H(24))(2)S(2)]·C(7)H(8), was obtained from the reaction of (ebthi)Zr(η(2)-Me(3)Si-C(2)-SiMe(3)) [ebthi is rac-1,2-bis-(η(5)-4,5,6,7-tetra-hydro-inden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile C N-ada. Each Zr(IV) atom is coordinated by the sterically hindered ebthi ligand and two μ-sulfide ligands in a strongly distorted tetra-hedral geometry. The [ZrS](2) unit is almost planar (mean deviation from the best plane of the four atoms = 0.025†à ). A -CH(2)-CH(2)- 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 mol-ecule.
