BaNdCuTe3 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 6-coordinate geometry to two equivalent Te(2) and six equivalent Te(1) atoms. Nd(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form NdTe6 octahedra that share corners with two equivalent Nd(1)Te6 octahedra, edges with two equivalent Nd(1)Te6 octahedra, and edges with four equivalent Cu(1)Te4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. Cu(1) is bonded to two equivalent Te(1) and two equivalent Te(2) atoms to form CuTe4 tetrahedra that share corners with two equivalent Cu(1)Te4 tetrahedra and edges with four equivalent Nd(1)Te6 octahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to three equivalent Ba(1), two equivalent Nd(1), and one Cu(1) atom. In the second Te site, Te(2) is bonded to two equivalent Ba(1), two equivalent Nd(1), and two equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing TeBa2Nd2Cu2 octahedra. The corner-sharing octahedra are not tilted.
BaNdCuTe3 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 6-coordinate geometry to two equivalent Te(2) and six equivalent Te(1) atoms. Both Ba(1)-Te(2) bond lengths are 3.50 Å. There are four shorter (3.54 Å) and two longer (4.09 Å) Ba(1)-Te(1) bond lengths. Nd(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form NdTe6 octahedra that share corners with two equivalent Nd(1)Te6 octahedra, edges with two equivalent Nd(1)Te6 octahedra, and edges with four equivalent Cu(1)Te4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. Both Nd(1)-Te(2) bond lengths are 3.12 Å. All Nd(1)-Te(1) bond lengths are 3.17 Å.
