The compound described by K4Be3O5 crystallizes in the monoclinic C2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to one O(1), two equivalent O(2), and three equivalent O(3) atoms. There are three inequivalent Be sites. In the first Be site, Be(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. In the second Be site, Be(2) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(3) atoms. In the third Be site, Be(3) is bonded in a distorted tetrahedral geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(3) is bonded in a 2-coordinate geometry to two equivalent K(1), three equivalent K(2), one Be(2), and one Be(3) atom. In the second O site, O(1) is bonded in a linear geometry to two equivalent K(1), two equivalent K(2), one Be(1), and one Be(2) atom. In the third O site, O(2) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), one Be(1), and one Be(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
