Bis(η^5-pentamethylcyclopentadienyl)-bis[μ-2,3,4,5-tetramethyl-1-methylene-ScC^1:Sc'(η^5)-cyclopentadienyl]-discandium(III), [Sc_2(C_(10)H_(15))_2-(C_(10)H_(14)_2], M_r = 628.90, triclinic, Pl, ɑ = 8.641 (5), b= 9.478 (2), c = 12.338 (5) Å, ɑ = 75.58 (3), β = 80.39 (4), y = 63.75 (3)º, V = 875.8 (7) Å^3, Z = 1, D_x = 1.19 g cm^(-3), λ(Mo Kɑ}=0.71073 Å, μ = 4.11 cm^(-1), F(000) = 340, room temperature, R (on F) = 0.046 for 2241 reflections with F_o^2 > 3σ(F_o^2). Two bis(pentamethylcyclopentadienyl)scandium molecules are joined across a center of symmetry. One of the Cp^* methyl groups has lost an H atom and that methylene group bonds to the symmetry-related Sc atom: Sc-C6' = 2.282 (5) Å. Other aspects of the bis-Cp^*Sc geometry are normal.
