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.
MgTh4 crystallizes in the cubic Fd-3m space group. Mg(1) is bonded in a tetrahedral geometry to four equivalent Th(1) atoms. All Mg(1)-Th(1) bond lengths are 2.94 Å. Th(1) is bonded in a 10-coordinate geometry to one Mg(1) and nine equivalent Th(1) atoms. There are three shorter (3.30 Å) and six longer (4.09 Å) Th(1)-Th(1) bond lengths.
