Abstract

KAlGeO4 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. there are six inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.85–3.22 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 2.76–2.78 Å. In the third 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 2.71–2.79 Å. In the fourth K1+ site, K1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.68–3.36 Å.
