Abstract

Ba4Nd2Cd3Se10 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Ba–Se bond distances ranging from 3.31–3.78 Å. In the second Ba2+ site, Ba2+ is bonded to seven Se2- atoms to form distorted BaSe7 pentagonal bipyramids that share corners with two equivalent NdSe6 octahedra, corners with two equivalent BaSe7 pentagonal bipyramids, edges with three NdSe6 octahedra, edges with three equivalent BaSe7 pentagonal bipyramids, edges with four CdSe4 tetrahedra, and faces with two equivalent BaSe7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 17°. There are a spread of Ba–Se bond distances ranging from 3.29–3.45 Å.
