Abstract

The reaction of [SiMe2(C5H4)2][(C5Me5)ZrMe2]2 with H2S at 110°C proceeds with the formation of [SiMe2(C5H4)2][(C5Me5)Zr(μ-S)]2]2. The molecular structure of this dinuclear zirconocenophane compound features a non-planar four-membered Zr2(μ-S)22 ring with two symmetrically-bridging sulfido groups. The bridging dimethylsilyl-bridged bis(cyclopentadienyl) ligand adopts a skewed orientation to accommodate the long Zr ... Zr separation of 3.611(1) Å. This compound crystallizes in the centrosymmetric space group P1 with refined lattice parameters ofa = 10.905(1) Å,b = 10.939(2) Å,c = 14.621(2) Å,α = 106.32(1)°,β = 91.25(1)°,γ = 111.25(1)°,V = 1545.1(8) Å3, ρcalc. = 1.512g/cm3,Z=2. Full-matrix refinement converged with final discrepancy indices of R(Fo = 0.045 andR(Fo) = 0.079 with GOF= 1.60 for 4403 data withFo > 3σ(Fo).
