Ba(LuTe2)2 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent Te(1), two equivalent Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to one Te(2), two equivalent Te(4), and three equivalent Te(3) atoms to form a mixture of edge and corner-sharing LuTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-57°. In the second Lu site, Lu(2) is bonded to one Te(4), two equivalent Te(2), and three equivalent Te(1) atoms to form a mixture of edge and corner-sharing LuTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-57°. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ba(1) and three equivalent Lu(2) atoms to form a mixture of distorted edge and corner-sharing TeBa2Lu3 trigonal bipyramids. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Lu(1), and two equivalent Lu(2) atoms. In the third Te site, Te(3) is bonded to two equivalent Ba(1) and three equivalent Lu(1) atoms to form a mixture of edge and corner-sharing TeBa2Lu3 square pyramids. In the fourth Te site, Te(4) is bonded to two equivalent Ba(1), one Lu(2), and two equivalent Lu(1) atoms to form a mixture of distorted edge and corner-sharing TeBa2Lu3 trigonal bipyramids.
Ba(LuTe2)2 crystallizes in the orthorhombic Pnma space group.
