Materials Data on Ba(CeS2)2 by Materials Project
Ba(CeS2)2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Ba2+ is bonded to eight equivalent S2- atoms to form distorted BaS8 hexagonal bipyramids that share corners with eight equivalent CeS8 hexagonal bipyramids, edges with four equivalent BaS8 hexagonal bipyramids, and faces with eight equivalent CeS8 hexagonal bipyramids. There are four shorter (3.09 Å) and four longer (3.23 Å) Ba–S bond lengths. Ce3+ is bonded to eight equivalent S2- atoms to form distorted CeS8 hexagonal bipyramids that share corners with four equivalent BaS8 hexagonal bipyramids, corners with four equivalent CeS8 hexagonal bipyramids, edges with four equivalent CeS8 hexagonal bipyramids, faces with four equivalent BaS8 hexagonal bipyramids, and faces with four equivalent CeS8 hexagonal bipyramids. There are a spread of Ce–S bond distances ranging from 2.86–3.22 Å. S2- is bonded in a 6-coordinate geometry to two equivalent Ba2+ and four equivalent Ce3+ atoms.
