Abstract
The compound [Cr3O(OOCPh)(6)(py)(3)](py)ClO4 crystallizes in a lattice of threefold symmetry with the trichromium clusters forming equilater al trianges at 173 It, but at 1.5 K the neutron scattering spectrum in dicates lower symmetry. Evidently the triangular clusters adopt nonequ ilateral structures which are concealed by rotational disorder in the crystal.
