From the unit cell volumes, we obtain the mean values of the intermolecular separations (assumed as the centroid to centroid distances): 13.9 for Fe17-trigonal and the slightly larger value of 14.6 for Fe17-cubic. CCDC-612322 and CCDC-612323 contain the supplementary crystallographic data for Fe17-cubic and Fe17-trigonal, respectively.
