In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.13–3.39 Å. In the fourth K1+ site, K1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.18–3.50 Å. In the fifth K1+ site, K1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.14–3.60 Å. In the sixth K1+ site, K1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.19–3.40 Å. There are three inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Zn–Cl bond distances ranging from 2.26–2.31 Å. In the second Zn2+ site, Zn2+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Zn–Cl bond distances ranging from 2.26–2.32 Å. In the third Zn2+ site, Zn2+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Zn–Cl bond distances ranging from 2.25–2.30 Å. There are twelve inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Zn2+ atom. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Zn2+ atom. In the third Cl1- site, Cl1- is bonded to four K1+ and one Zn2+ atom to form a mixture of distorted edge and corner-sharing ClK4Zn trigonal bipyramids. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to five K1+ and one Zn2+ atom. In the fifth Cl1- site, Cl1- is bonded to four K1+ and one Zn2+ atom to form a mixture of distorted edge and corner-sharing ClK4Zn trigonal bipyramids.
