The structure described by Li4Bi2O5 crystallizes in the orthorhombic Pnna space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted edge-sharing LiO4 trigonal pyramids. In the second Li site, Li(2) is bonded in a linear geometry to two equivalent O(3) atoms. In the third Li site, Li(3) is bonded in a linear geometry to two equivalent O(2) atoms. Bi(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Li(3), two equivalent Li(1), and one Bi(1) atom. In the third O site, O(3) is bonded to two equivalent Li(2) and two equivalent Bi(1) atoms to form distorted corner-sharing OLi2Bi2 tetrahedra. is represented by the CIF card [CIF]
