摘要：

Attempts to synthesize titanium(IV) neopentoxide led to two unique products which were crystallographically characterized. A metathesis reaction between TiCl4 and NaOCH2CMe3 (NaONp) yielded Ti-3(O)(Cl)(ONp)(9) . C7H8, 1, which adopts a standard M-3(mu(3)-X)(2)(mu-X)(3)X-6 structure. The mu(3) ligands are a Cl and an O atom, with the lest of ligands represented by bridging and terminal ONp ligands. [Ti(ONp)(4)](2), 2, was isolated in high yield by an alcoholysis exchange between Ti(OPri)(4) and HONp. 2 adopts a typical M-2(mu-X)(2)(X)(6) fused axial-equatorial edge-shared geometry, wherein each metal center is 5 coordinated. On the basis of molecular weight solution studies and H-1, C-13, O-17 (natural abundance), and Ti-47,Ti-49 solution and solid-state NMR investigations, 2 was determined to be a monomer in solution.
