Title: Materials Data on CsNa2 by Materials Project

Abstract

Na2Cs is Hexagonal Laves structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Cs is bonded in a 12-coordinate geometry to four equivalent Cs and twelve Na atoms. There are a spread of Cs–Cs bond distances ranging from 4.73–4.79 Å. There are a spread of Cs–Na bond distances ranging from 4.55–4.58 Å. There are four inequivalent Na sites. In the first Na site, Na is bonded to six equivalent Cs and six Na atoms to form a mixture of corner, edge, and face-sharing NaCs6Na6 cuboctahedra. There are two shorter (3.88 Å) and four longer (3.89 Å) Na–Na bond lengths. In the second Na site, Na is bonded to six equivalent Cs and six Na atoms to form a mixture of corner, edge, and face-sharing NaCs6Na6 cuboctahedra. There are a spread of Na–Na bond distances ranging from 3.89–3.91 Å. In the third Na site, Na is bonded to six equivalent Cs and six Na atoms to form a mixture of corner, edge, and face-sharing NaCs6Na6 cuboctahedra. There are one shorter (3.88 Å) and one longer (3.90 Å) Na–Na bond lengths. In the fourth Na site, Na is bonded to six equivalent Cs and six Na atoms tomore » form a mixture of corner, edge, and face-sharing NaCs6Na6 cuboctahedra.« less
