Materials Data on RbNpCuS3 by Materials Project
RbNpCuS3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Rb–S bond distances ranging from 3.38–3.66 Å. Np4+ is bonded to six S2- atoms to form NpS6 octahedra that share corners with two equivalent NpS6 octahedra, edges with two equivalent NpS6 octahedra, and edges with four equivalent CuS4 tetrahedra. The corner-sharing octahedral tilt angles are 35°. There are two shorter (2.69 Å) and four longer (2.71 Å) Np–S bond lengths. Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with two equivalent CuS4 tetrahedra and edges with four equivalent NpS6 octahedra. There are two shorter (2.30 Å) and two longer (2.40 Å) Cu–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to three equivalent Rb1+, two equivalent Np4+, and one Cu1+ atom. In the second S2- site, S2- is bonded in a 6-coordinate geometry to two equivalent Rb1+, two equivalent Np4+, and two equivalent Cu1+ atoms.
