DOI: 10.1021/acs.inorgchem.1c01277
Abstract: In lead(II) halide compounds including virtually all lead halide perovskites, the Pb2+ 6s lone pair results in distorted octahedra, in accordance with the pseudo-Jahn-Teller effect, rather than generating hemihedral coordination polyhedra. Here, in contrast, we… read more here.
