A dimeric constrained-geometry titanium complex linked by double Ti-CH2-Al-CH2 heterocycles.
In the structure of bis([N-[dimethyl(1eta5-2,3,4,6-tetramethylindenyl)silyl]cyclohexylamido-1kappaN](methyl-3kappaC)-di-mu3-methylene-1:2:3kappa3C;1:3:3'kappa3C-tris(pentafluorophenyl-2kappaC)titanium) benzene disolvate, [Me2Si(eta5-2,3,4,6-Me4C9H2)(C6H11N)]Ti[(mu3-CH2)Al(C6F5)3][AlMe(mu3-CH2)]2 or [Ti2(C21H7AlF15)2(C21H31NSi)2].2C6D6, the dimer is located on an inversion center, and the two Ti centers are linked by double Ti(mu3-CH2)Al(C6F5)3AlMe(mu3-CH2) heterocycles. The electron-deficient Ti centers are further stabilized by two alpha-agostic interactions between Ti and one H atom of each bridging methylene group.
