The material structure described by K2PbO3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Pb(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing PbO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent K(1) and two equivalent Pb(1) atoms to form a mixture of distorted corner, edge, and face-sharing OK4Pb2 octahedra. The corner-sharing octahedral tilt angles range from 37-55°. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Pb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
