The chlorine coordinated ligands in [Ti(tfba)2Cl2] (Htfba = 4,4,4-trifluoro-1-(phenyl)-1,3-butanedione = PhCOCH2COCF3) are very susceptible to hydrolysis and even with trace amounts of water, the formation of hydrolysed complexes, dinuclear {Ti(tfba)2Cl}2(mu-O) or tetranuclear [Ti(tfba)2(mu-O)]4, take place, whereas with an excess of water, decomposition to TiO2occurs. Substitution of the chloro-ligands in [Ti(tfba)2Cl2] with H2biphen (H2biphen = 2,2?-dihydroxybiphenyl or biphenol) leads to [Ti(tfba)2biphen] with enhanced water stability. Experimentally, two steps were observed for the substitution [Ti(tfba)2Cl2] + H2biphen. Computational chemistry calculations reveal that each step involves several transition states, with formation of a 7-coordinated intermediate in the first reaction half. Location of this intermediate is dependent on inclusion of empirical dispersion-corrections in the functional. The three geometrical cis-isomers of [Ti(tfba)2biphen] were observed in solution using low temperature1H and19F NMR, whereas in the solid state, two of the isomers, cis-cis-trans and cis-trans-cis, crystallized in the same unit cell. The crystal structure of the hydrolysed tetranuclear complex [Ti(tfba)2(mu-O)]4is composed of four identical cis-cis-trans isomers of [Ti(tfba)2Cl2]. The eight beta-diketonato backbones and the four bridging oxygens have a S4molecular symmetry.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 1806-29-7. In my other articles, you can also check out more blogs about 1806-29-7
