MgSc3Ru2 crystallizes in the tetragonal P4/mmm space group. Mg(1) is bonded to four equivalent Mg(1) and eight equivalent Sc(2) atoms to form a mixture of corner and face-sharing MgMg4Sc8 cuboctahedra. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a body-centered cubic geometry to eight equivalent Ru(1) atoms. In the second Sc site, Sc(2) is bonded in a 4-coordinate geometry to four equivalent Mg(1) and four equivalent Ru(1) atoms. Ru(1) is bonded in a body-centered cubic geometry to four equivalent Sc(1) and four equivalent Sc(2) atoms.
