A complex pattern: Single-phase brookite, rutile, and rutile–anatase nanoparticles can be prepared from the new water-soluble titanium(IV) complex (NH4)6[Ti4(C2H2O3)4(C2H3O3)2(O2)4O2]⋅4 H2O. It appears that the structural similarity of the complex anion to the brookite architecture allows the directional synthesis of brookite nanopowders in a pure form (see scheme).
