MgScInPb crystallizes in the trigonal R3m space group. Mg(1) is bonded in a distorted single-bond geometry to one Sc(1) atom. The Mg(1)-Sc(1) bond length is 1.75 Å. Sc(1) is bonded in a 5-coordinate geometry to one Mg(1), one In(1), and three equivalent Pb(1) atoms. The Sc(1)-In(1) bond length is 1.75 Å. All Sc(1)-Pb(1) bond lengths are 3.15 Å. In(1) is bonded in a linear geometry to one Sc(1) and one Pb(1) atom. The In(1)-Pb(1) bond length is 1.75 Å. Pb(1) is bonded in a distorted single-bond geometry to three equivalent Sc(1) and one In(1) atom.
