Materials Data on Al2PbSe4 by Materials Project
Al2PbSe4 is I4/mcm-derived structured and crystallizes in the orthorhombic Cccm space group. The structure is three-dimensional. Al3+ is bonded to four Se2- atoms to form edge-sharing AlSe4 tetrahedra. There are a spread of Al–Se bond distances ranging from 2.41–2.44 Å. Pb2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are four shorter (3.26 Å) and four longer (3.31 Å) Pb–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted L-shaped geometry to two equivalent Al3+ and two equivalent Pb2+ atoms. In the second Se2- site, Se2- is bonded in a distorted L-shaped geometry to two equivalent Al3+ and two equivalent Pb2+ atoms.
