icositetrahedra have been synthesized by a facile hydrothermal synthesis method in the presence of dihydrogen phosphate ions. The icositetrahedron particles are of hexagonal shape and enclosed by 24 quadrilaterals. It could be seen as a particle with six equivalent {110} facets added to the truncated hexagonal bipyramidal structure, that is, it is enclosed by six {110} planes, six {104} planes and twelve {113} planes. Dihydrogen phosphate ions play an important role in the formation of α-Fe
