Hi Cyrus, In a rectangular box (which is a specific case of a triclinic box) your molecule can't rotate freely without significant chance to run into its periodic image, invalidating whatever result you get. So, unless rotation is of no concern, or can be cirrcumvented, you'll need to use a rhombic dodecahedron.
