Al Al Te Os
OsAl2Te is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsAl2Te clusters. Os(1) is bonded in a 2-coordinate geometry to two equivalent Al(1) atoms. Both Os(1)-Al(1) bond lengths are 0.40 Å. Al(1) is bonded in a distorted single-bond geometry to one Os(1) and one Te(1) atom. The Al(1)-Te(1) bond length is 0.18 Å. Te(1) is bonded in a water-like geometry to two equivalent Al(1) atoms.
