Abstract
K3Nb7O19 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to eleven O2- atoms. There are a spread of K–O bond distances ranging from 2.70–3.39 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.73–2.85 Å. In the third K1+ site, K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.85–3.42 Å. There are seven inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 0–12°. There are a spread of Nb–O bond distances ranging from 1.94–2.11 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 0–10°. There are a spread of Nb–O bond distances ranging from 1.90–2.17 Å. In the third Nb5+ site, Nb5+ is bondedmore »
