Materials Data on CdBiS2Cl by Materials Project
CdBiS2Cl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cd2+ is bonded to four S2- and two equivalent Cl1- atoms to form a mixture of corner and edge-sharing CdS4Cl2 octahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Cd–S bond distances ranging from 2.63–2.84 Å. Both Cd–Cl bond lengths are 2.69 Å. Bi3+ is bonded in a 7-coordinate geometry to five S2- and two equivalent Cl1- atoms. There are a spread of Bi–S bond distances ranging from 2.62–3.01 Å. Both Bi–Cl bond lengths are 3.46 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Cd2+ and two equivalent Bi3+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Cd2+ and three equivalent Bi3+ atoms. Cl1- is bonded in a distorted L-shaped geometry to two equivalent Cd2+ and two equivalent Bi3+ atoms.
