Abstract
KTm2F7 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.65–2.92 Å. In the second K1+ site, K1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of K–F bond distances ranging from 2.64–2.72 Å. In the third K1+ site, K1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of K–F bond distances ranging from 2.65–2.71 Å. In the fourth K1+ site, K1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.66–2.93 Å. There are five inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded in a body-centered cubic geometry to eight F1- atoms. There are a spread of Tm–F bond distances ranging from 2.17–2.40 Å. In the second Tm3+ site, Tm3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Tm–F bond distances ranging from 2.18–2.39 Å. In the third Tm3+ site, Tm3+ ismore »
