Structural and Physical Properties of Two Distinct 2D Lead Halides with Intercalated Cu(II).

Transition metal cation intercalation between the layers of two-dimensional (2D) metal halides is an underexplored research area. In this work we focus on the synthesis and physical property characterizations of two layered hybrid lead halides: a new compound [Cu(OC-CH-NH)]PbBr and the previously reported [Cu(OC-(CH)-NH)]PbBr. These compounds exhibit 2D layered crystal structures with incorporated Cu between the metal halide layers, which is achieved by combining Cu(II) and lead bromide with suitable amino acid precursors.
