Ru2Te crystallizes in the trigonal R3m space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Ru(2) and three equivalent Te(1) atoms. The Ru(1)-Ru(2) bond length is 0.19 Å. All Ru(1)-Te(1) bond lengths are 3.07 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Ru(1) and three equivalent Te(1) atoms. All Ru(2)-Te(1) bond lengths are 2.86 Å. Te(1) is bonded to three equivalent Ru(1) and three equivalent Ru(2) atoms to form edge-sharing TeRu6 octahedra.
