Mn3Cd is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mn(2) and four equivalent Cd(1) atoms. In the second Mn site, Mn(2) is bonded in a 14-coordinate geometry to eight equivalent Mn(1) and six equivalent Cd(1) atoms. Cd(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mn(2) and eight equivalent Mn(1) atoms.
