LiBeHfSn crystallizes in the trigonal R3m space group. Li(1) is bonded in a single-bond geometry to one Be(1), four equivalent Hf(1), and three equivalent Sn(1) atoms. The Li(1)-Be(1) bond length is 0.67 Å. There are three shorter (2.73 Å) and one longer (3.36 Å) Li(1)-Hf(1) bond length. All Li(1)-Sn(1) bond lengths are 2.70 Å. Be(1) is bonded in a single-bond geometry to one Li(1), three equivalent Hf(1), and three equivalent Sn(1) atoms. All Be(1)-Hf(1) bond lengths are 2.70 Å. All Be(1)-Sn(1) bond lengths are 2.73 Å. Hf(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), three equivalent Be(1), and three equivalent Sn(1) atoms. All Hf(1)-Sn(1) bond lengths are 2.70 Å. Sn(1) is bonded in a 9-coordinate geometry to three equivalent Li(1), three equivalent Be(1), and three equivalent Hf(1) atoms.
