N2 - The synthesis and structures of zirconium and titanium trisiloxides containing the tridentate ligand [MeSi(RMeSiO) 3] 3- (rac-l,l-3)-3H (R = Si(SiMe 3) 2Me) are reported. Reactions of rac-1,1-3 with M(OEt) 4, where M = Ti or Zr, gave tridentate complexes of formula [MeSi(RMeSiO) 3]MOEt (1,1-4, M = Ti; 1,1-5, M = Zr). In striking contrast, treatment of rac-1,1-3 with Zr(NEt) 4 afforded the spirocyclic complex {[MeSi(RMeSiO) 3] 2Zr} H 2 (1,1-7). These compounds feature bicyclooctane structures, which are hitherto unknown in the chemistry of metal siloxides.
