The crystal structure described by Rb2Be2Zn(O3F4)2 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one F(1), one F(3), two equivalent F(4), and three equivalent F(2) atoms. Be(1) is bonded in a tetrahedral geometry to one F(1), one F(2), one F(3), and one F(4) atom. Zn(1) is bonded in a distorted octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Rb(1) and one Zn(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Rb(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Zn(1) atom. There are four inequivalent F sites. In the first F site, F(4) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Be(1) atom. In the second F site, F(1) is bonded in a distorted single-bond geometry to one Rb(1) and one Be(1) atom. In the third F site, F(2) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Be(1) atom. In the fourth F site, F(3) is bonded in a distorted single-bond geometry to one Rb(1) and one Be(1) atom. is represented by the CIF card [CIF]
