The structure described by K2BeCl4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to two equivalent Cl(3), three equivalent Cl(2), and four equivalent Cl(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to one Cl(2), three equivalent Cl(3), and four equivalent Cl(1) atoms. Be(1) is bonded in a tetrahedral geometry to one Cl(2), one Cl(3), and two equivalent Cl(1) atoms. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent K(2), and one Be(1) atom. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to one K(2), three equivalent K(1), and one Be(1) atom. In the third Cl site, Cl(3) is bonded in a distorted single-bond geometry to two equivalent K(1), three equivalent K(2), and one Be(1) atom. is represented by the CIF card [CIF]
