Materials Data on KGaCl4 by Materials Project
KGaCl4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to nine Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.30–3.91 Å. Ga3+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are one shorter (2.19 Å) and three longer (2.21 Å) Ga–Cl bond lengths. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Ga3+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Ga3+ atom. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to three equivalent K1+ and one Ga3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to two equivalent K1+ and one Ga3+ atom.
