MgYHfIn crystallizes in the trigonal R3m space group. Mg(1) is bonded to one Hf(1) and three equivalent In(1) atoms to form distorted corner-sharing MgHfIn3 trigonal pyramids. The Mg(1)-Hf(1) bond length is 1.89 Å. All Mg(1)-In(1) bond lengths are 3.07 Å. Y(1) is bonded in a single-bond geometry to one In(1) atom. The Y(1)-In(1) bond length is 1.89 Å. Hf(1) is bonded in a 1-coordinate geometry to one Mg(1) and one In(1) atom. The Hf(1)-In(1) bond length is 1.89 Å. In(1) is bonded in a distorted linear geometry to three equivalent Mg(1), one Y(1), and one Hf(1) atom.
