K2Be2O3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to one Be(1), two equivalent O(1), and four equivalent O(2) atoms. Be(1) is bonded in a distorted trigonal planar geometry to one K(1), one O(1), and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent K(1) and two equivalent Be(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Be(1) atoms.
K2Be2O3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to one Be(1), two equivalent O(1), and four equivalent O(2) atoms. The K(1)-Be(1) bond length is 3.02 Å. There is one shorter (2.73 Å) and one longer (3.20 Å) K(1)-O(1) bond length. There are a spread of K(1)-O(2) bond distances ranging from 2.68-3.27 Å. Be(1) is bonded in a distorted trigonal planar geometry to one K(1), one O(1), and two equivalent O(2) atoms. The Be(1)-O(1) bond length is 1.49 Å. Both Be(1)-O(2) bond lengths are 1.58 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent K(1) and two equivalent Be(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Be(1) atoms.
