Abstract
KSnO2 is Krennerite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.29 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.64–2.88 Å. In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.64–2.89 Å. In the fourth K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.80–3.31 Å. There are four inequivalent Sn3+ sites. In the first Sn3+ site, Sn3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.08–2.14 Å. In the second Sn3+ site, Sn3+ is bonded to six O2- atoms to form edge-sharing SnO6 octahedra. There are a spread of Sn–O bond distances ranging from 2.07–2.29 Å. In themore »
