Materials Data on K2CdSn by Materials Project

Abstract

K2CdSn crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 4-coordinate geometry to two equivalent Cd and four equivalent Sn atoms. Both K–Cd bond lengths are 3.96 Å. There are a spread of K–Sn bond distances ranging from 3.76–3.86 Å. In the second K site, K is bonded in a 4-coordinate geometry to two equivalent Cd and four equivalent Sn atoms. Both K–Cd bond lengths are 4.00 Å. There are a spread of K–Sn bond distances ranging from 3.73–3.90 Å. Cd is bonded in a distorted linear geometry to four K and two equivalent Sn atoms. Both Cd–Sn bond lengths are 2.83 Å. Sn is bonded in a 10-coordinate geometry to eight K and two equivalent Cd atoms.
