Materials Data on RbPbCl3 by Materials Project
RbPbCl3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.31–3.69 Å. Pb2+ is bonded to six Cl1- atoms to form a mixture of edge and corner-sharing PbCl6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are two shorter (2.90 Å) and four longer (2.95 Å) Pb–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded to three equivalent Rb1+ and two equivalent Pb2+ atoms to form distorted ClRb3Pb2 trigonal bipyramids that share corners with four equivalent ClRb2Pb2 tetrahedra, corners with nine equivalent ClRb3Pb2 trigonal bipyramids, edges with three equivalent ClRb2Pb2 tetrahedra, and edges with six equivalent ClRb3Pb2 trigonal bipyramids. In the second Cl1- site, Cl1- is bonded to two equivalent Rb1+ and two equivalent Pb2+ atoms to form distorted ClRb2Pb2 tetrahedra that share corners with four equivalent ClRb2Pb2 tetrahedra, corners with eight equivalent ClRb3Pb2 trigonal bipyramids, and edges with six equivalent ClRb3Pb2 trigonal bipyramids.
