In the first 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 3.05–3.69 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.28–3.90 Å. In the third 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 3.16–3.67 Å. There are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded in an octahedral geometry to six Cl1- atoms. There are a spread of Gd–Cl bond distances ranging from 2.67–2.70 Å. In the second Gd3+ site, Gd3+ is bonded in an octahedral geometry to six Cl1- atoms. There are a spread of Gd–Cl bond distances ranging from 2.63–2.71 Å. There are six inequivalent Cl1- sites.
