Materials Data on CaUS2 by Materials Project
CaUS2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Ca is bonded in a distorted rectangular see-saw-like geometry to four equivalent S atoms. All Ca–S bond lengths are 2.72 Å. U is bonded in a 4-coordinate geometry to four equivalent S atoms. There are two shorter (2.74 Å) and two longer (2.76 Å) U–S bond lengths. S is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ca and two equivalent U atoms.
