BaNdAgS3 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent S(2) and six equivalent S(1) atoms. Nd(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form NdS6 octahedra that share corners with two equivalent Nd(1)S6 octahedra, edges with two equivalent Nd(1)S6 octahedra, and edges with four equivalent Ag(1)S4 tetrahedra. The corner-sharing octahedral tilt angles are 44°. Ag(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form AgS4 tetrahedra that share corners with two equivalent Ag(1)S4 tetrahedra and edges with four equivalent Nd(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to three equivalent Ba(1), two equivalent Nd(1), and one Ag(1) atom. In the second S site, S(2) is bonded to two equivalent Ba(1), two equivalent Nd(1), and two equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing SBa2Nd2Ag2 octahedra. The corner-sharing octahedra are not tilted.
BaNdAgS3 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent S(2) and six equivalent S(1) atoms. Both Ba(1)-S(2) bond lengths are 3.14 Å. There are four shorter (3.37 Å) and two longer (3.59 Å) Ba(1)-S(1) bond lengths. Nd(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form NdS6 octahedra that share corners with two equivalent Nd(1)S6 octahedra, edges with two equivalent Nd(1)S6 octahedra, and edges with four equivalent Ag(1)S4 tetrahedra. The corner-sharing octahedral tilt angles are 44°. Both Nd(1)-S(2) bond lengths are 2.87 Å. All Nd(1)-S(1) bond lengths are 2.89 Å. Ag(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form AgS4 tetrahedra that share corners with two equivalent Ag(1)S4 tetrahedra and edges with four equivalent Nd(1)S6 octahedra.
