History
editTitanium(IV) acetate has been discussed in archaic literature,[2] well before the advent of X-ray crystallography and an appreciation of the structural trends in metal carboxylate complexes.[3] A variety of titanium oxo acetates were prepared by reactions of titanium alkoxides and acetic acid.[4]
Uses
editSpecies claimed to be titanium(IV) acetate have been used in the production of bismuth titanate ferroelectric thin films. Titanium(IV) acetate is used in the step of making the acetate-derived solutions. The acetate derived solutions were created by blending acetic acid and bismuth acetate together and adding titanium(IV) acetate.[5] "Titanium(IV) acetate" is a substitute for antimony potassium tartrate(emetic tartar) when making red and brown dyes.[6]
Related compounds
editTi(IV) complexes containing only carboxylate ligands have eluded crystallographic characterization, but various polycarboxylate species are known. One example is [Ti(edta)(OH2)].[7]
