Crystal packing in the cubic form. (a) A view along the body diagonal of the I432 unit cell with unit-cell parameter 285.7 Å depicts a sparse molecular packing. (b) A tail-to-tail crystal contact between trimers (blue circle) along the body diagonal and a head-to-head contact between the adjacent trimers (green square) at the centre of the cube stabilizes this arrangement. (c) The unique arrangement of the molecules in I432 crystals results in large solvent channels as viewed along the diagonal (left) and the plane (right) of the cube.
