Materials Data on K6Cu(SiO4)2 by Materials Project
K6Cu(SiO4)2 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 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.66–3.24 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 2.68–2.95 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 2.75–3.13 Å. Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.98 Å) and two longer (1.99 Å) Cu–O bond length. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.64 Å) and two longer (1.69 Å) Si–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to five K1+ and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to six K1+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 6-coordinate geometry to four K1+, one Cu2+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to three K1+, one Cu2+, and one Si4+ atom.
