RuFe4Te crystallizes in the trigonal R3m space group. Ru(1) is bonded in a 9-coordinate geometry to three equivalent Fe(1), three equivalent Fe(2), and three equivalent Te(1) atoms. All Ru(1)-Fe(1) bond lengths are 2.83 Å. All Ru(1)-Fe(2) bond lengths are 2.83 Å. All Ru(1)-Te(1) bond lengths are 2.94 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 3-coordinate geometry to one Ru(1), one Fe(2), two equivalent Fe(1), and one Te(1) atom. The Fe(1)-Fe(2) bond length is 2.17 Å. Both Fe(1)-Fe(1) bond lengths are 1.25 Å. The Fe(1)-Te(1) bond length is 2.49 Å. In the second Fe site, Fe(2) is bonded in a 9-coordinate geometry to three equivalent Ru(1), three equivalent Fe(1), and three equivalent Te(1) atoms. All Fe(2)-Te(1) bond lengths are 2.92 Å. Te(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1), three equivalent Fe(1), and three equivalent Fe(2) atoms.
