TaNbMoSn crystallizes in the trigonal R3m space group. Ta(1) is bonded in a 11-coordinate geometry to four equivalent Nb(1), four equivalent Mo(1), and three equivalent Sn(1) atoms. There are three shorter (2.71 Å) and one longer (3.66 Å) Ta(1)-Nb(1) bond length. There are three shorter (2.71 Å) and one longer (3.92 Å) Ta(1)-Mo(1) bond length. All Ta(1)-Sn(1) bond lengths are 2.71 Å. Nb(1) is bonded in a single-bond geometry to four equivalent Ta(1) and one Sn(1) atom. The Nb(1)-Sn(1) bond length is 0.26 Å. Mo(1) is bonded in a 3-coordinate geometry to four equivalent Ta(1) atoms. Sn(1) is bonded in a single-bond geometry to three equivalent Ta(1) and one Nb(1) atom.
