A complex pattern : Single‐phase brookite, rutile, and rutile–anatase nanoparticles can be prepared from the new water‐soluble titanium( IV ) complex (NH 4 ) 6 [Ti 4 (C 2 H 2 O 3 ) 4 (C 2 H 3 O 3 ) 2 (O 2 ) 4 O 2 ]⋅4 H 2 O. 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).
