Abstract

A novel titanium phenylphosphonate alkoxide complex, [Ti-6(mu(3)-O)(2)(mu-OEt)(6)(mu(2)-OEt)(6)(mu(3)-PPA)(4)]center dot 0.5C(7)H(8) (1) was synthesized by solvothermal processing and its structure was determined by single crystal Xray diffraction. The solution stability was characterized in solution by H-1 NMR, C-13 NMR and P-31 NMR and 1H DOSY NMR and compared with a previously reported titanium phenylphosphonate alkoxide complex [(Ti4O(OEt)(12)PPA] (2) of similar size. According to the NMR analyses, the solid-state structure is predominantly retained in solution for both 1 and 2. P-31 NMR and H-1 DOSY NMR of the mother liquor from the synthesis of 2 indicated presence of traces of at least two other complexes which could not be isolated in pure form. (C) 2019 Elsevier Ltd.
