Abstract
The title dimeric zirconium complex, [Zr2(C20H24)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 = 0.025 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.

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
