The material described by Ba(AlTe2)2 crystallizes in the tetragonal I422 space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. Al(1) is bonded to four equivalent Te(1) atoms to form edge-sharing AlTe4 tetrahedra. Te(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
