Pair distribution function analysis of in situ total scattering data recorded during formation of WO 3 nanocrystals under hydrothermal conditions reveal that a complex precursor structure exists in solution. The WO 6 polyhedra of the precursor cluster undergo reorientation before forming the nanocrystal. This reorientation is the critical element in the formation of different hexagonal polymporphs of WO 3 .
