In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.31–3.52 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.32–3.60 Å. In the third Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.34–3.63 Å. In the fourth Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.31–3.53 Å. In the fifth Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.31–3.59 Å. In the sixth Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to seven Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.36–3.96 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 2.27–2.32 Å.

In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three Rb1+ and one Zn2+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Rb1+ and one Zn2+ atom. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Rb1+ and one Zn2+ atom. In the fourth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three Rb1+ and one Zn2+ atom. In the fifth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Rb1+ and one Zn2+ atom. In the sixth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three Rb1+ and one Zn2+ atom. In the seventh Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Rb1+ and one Zn2+ atom. In the eighth Cl1- site, Cl1- is bonded to four Rb1+ and one Zn2+ atom to form a mixture of distorted edge and corner-sharing ClRb4Zn trigonal bipyramids. In the ninth Cl1- site, Cl1- is bonded in a distorted rectangular see-saw-like geometry to three Rb1+ and one Zn2+ atom.
