Ba Ba Te Ru
Ba2RuTe crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a single-bond geometry to three equivalent Ru(1) and one Te(1) atom. There are a spread of Ba(1)-Ru(1) bond distances ranging from 3.01-3.64 Å. The Ba(1)-Te(1) bond length is 1.59 Å. Ru(1) is bonded in a 8-coordinate geometry to six equivalent Ba(1) and two equivalent Te(1) atoms. There is one shorter (2.90 Å) and one longer (2.97 Å) Ru(1)-Te(1) bond length. Te(1) is bonded in a water-like geometry to two equivalent Ba(1) and two equivalent Ru(1) atoms.
