Acentric crystalline materials are the cornerstone of numerous cutting-edge technologies and have been highly sought-after, but they are difficult to construct controllably. Herein, by introducing a new p-block element to break the symmetrical environment of the d transition metal in the centric matrix TiTeO, a novel acentric tellurite sulfate, namely Ti(TeO)(SO), was successfully constructed. In its structure, two types of p-block element-centered oxo-anionic groups, [TeO] and [SO], endow [TiO] with an out-of-center distortion along the local C[111] direction, which is rare in titanium oxides containing a lone-pair cation.
