Materials Data on Rb2Pb2O3 by Materials Project
Rb2Pb2O3 crystallizes in the cubic I2_13 space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (3.03 Å) and three longer (3.14 Å) Rb–O bond lengths. Pb2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent O2- atoms. All Pb–O bond lengths are 2.21 Å. O2- is bonded to four equivalent Rb1+ and two equivalent Pb2+ atoms to form a mixture of distorted edge, face, and corner-sharing ORb4Pb2 octahedra. The corner-sharing octahedra tilt angles range from 50–61°.
