Materials Data on Cd4FeS5 by Materials Project
FeCd4S5 is Enargite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to four S2- atoms to form FeS4 tetrahedra that share corners with four FeS4 tetrahedra and corners with eight CdS4 tetrahedra. There are a spread of Fe–S bond distances ranging from 2.36–2.44 Å. In the second Fe2+ site, Fe2+ is bonded to four S2- atoms to form FeS4 tetrahedra that share corners with four FeS4 tetrahedra and corners with eight CdS4 tetrahedra. There are a spread of Fe–S bond distances ranging from 2.38–2.43 Å. There are eight inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to four S2- atoms to form CdS4 tetrahedra that share corners with two equivalent FeS4 tetrahedra and corners with ten CdS4 tetrahedra. There are a spread of Cd–S bond distances ranging from 2.55–2.59 Å. In the second Cd2+ site, Cd2+ is bonded to four S2- atoms to form CdS4 tetrahedra that share corners with six FeS4 tetrahedra and corners with six CdS4 tetrahedra. There are a spread of Cd–S bond distances ranging from 2.58–2.62 Å. In the third Cd2+ site, Cd2+ is bonded to four S2- atoms to form CdS4 tetrahedra that share corners with four equivalent FeS4 tetrahedra and corners with eight CdS4 tetrahedra.
