The first titanium(IV) complexes with cyclic tetrasiloxide ligands, [Ti(L1H)(OSiMe3)]2(H2O) (1) and (CpTiCl)4(L2)2 (2), were synthesized using the all-cis isomer of cyclotetrasiloxanetetraols R4(SiO)4(OH)4 (L1H4: R = Ph, L2H4: R = iPr) as ligand precursors. X-ray analysis revealed that 1 is a dinuclear complex with bridging siloxy and aqua ligands while 2 has a tetranuclear cage structure capped by two L2 ligands.
