Materials Data on CsEuS2 by Materials Project
CsEuS2 is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six equivalent S2- atoms. All Cs–S bond lengths are 3.53 Å. Eu3+ is bonded to six equivalent S2- atoms to form edge-sharing EuS6 octahedra. All Eu–S bond lengths are 2.87 Å. S2- is bonded to three equivalent Cs1+ and three equivalent Eu3+ atoms to form a mixture of distorted edge, face, and corner-sharing SCs3Eu3 octahedra. The corner-sharing octahedra tilt angles range from 0–41°.
