Materials Data on CaPbI4 by Materials Project
Abstract
CaPbI4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ca2+ is bonded to six I1- atoms to form CaI6 octahedra that share corners with two equivalent CaI6 octahedra, corners with three equivalent PbI6 octahedra, an edgeedge with one CaI6 octahedra, and edges with three equivalent PbI6 octahedra. The corner-sharing octahedra tilt angles range from 11–57°. There are a spread of Ca–I bond distances ranging from 3.06–3.26 Å. Pb2+ is bonded to six I1- atoms to form PbI6 octahedra that share corners with two equivalent PbI6 octahedra, corners with three equivalent CaI6 octahedra, an edgeedge with one PbI6 octahedra, and edges with three equivalent CaI6 octahedra. The corner-sharing octahedra tilt angles range from 11–59°. There are a spread of Pb–I bond distances ranging from 3.08–3.64 Å. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded in a 3-coordinate geometry to one Ca2+ and two equivalent Pb2+ atoms. In the second I1- site, I1- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ca2+ and two equivalent Pb2+ atoms. In the third I1- site, I1- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one Pb2+ atom. In the fourthmore »
