Materials Data on CsC by Materials Project

Abstract

CCs crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded to five C atoms to form distorted edge-sharing CsC5 square pyramids. There are a spread of Cs–C bond distances ranging from 3.33–3.53 Å. In the second Cs site, Cs is bonded in a 4-coordinate geometry to seven C atoms. There are a spread of Cs–C bond distances ranging from 3.31–3.59 Å. There are two inequivalent C sites. In the first C site, C is bonded in a 6-coordinate geometry to six Cs and one C atom. The C–C bond length is 1.27 Å. In the second C site, C is bonded in a 7-coordinate geometry to six Cs and one C atom.
