title: Unprecedented Dawson isomerism induced by a central [WO5] and four 45°-rotated belt square pyramids.
abstract: The seventh type of Wells-Dawson isomer, δ-[(WO(5))W(17)Cu(H(2)O)O(55)](10-) (1a) was obtained as a consequence of the formation of the first central square-pyramidal [WO(5)] moiety that results in a 45° rotation of the four belt [CuO(5)]/[WO(5)] square pyramids, establishing a new type of WD isomerism involving the rotation of the belt polyhedra, that were previously believed to stay unchanged.
