The reaction of nido-[NMe4]{7-SMe-8-Me-7,8-C2B9H10} with [RuCl2(PPh3)3] leads to the formation of [RuCl{7-SMe-8-Me-7,8-(5)-C2B8H11}(PPh 3)2]. The new C2B8 carborane ligand has a peculiar arachno structure that results from eliminating B(5) in the former C2B9H12- nido precursor. The geometry is basketlike with a B-B handle. The reaction takes place for other {7-SR-8-Me-7,8-C2B9H10}- ligands, R = Me, Et, iPr, nBu, and benzyl. The complex was characterized (R = Me) by an X-ray diffraction study. Dark red crystals were monoclinic, space group Pn (No. 7), with Z = 2, a = 10.751(2) ?, b = 14.369(3) ?, c = 16.073(3) ?, β = 95.83(1)°, V = 2470(1) ?3, and Rw(Fo) = 0.063 for 3957 reflections having I ≥ 2.5σ(I).
