The material structure described by MgTh4 crystallizes in the cubic Fd-3m space group. Mg(1) is bonded in a tetrahedral geometry to four equivalent Th(1) atoms. Th(1) is bonded in a 10-coordinate geometry to one Mg(1) and nine equivalent Th(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
