Chiral hybrid organic-inorganic metal halides have garnered broad attention due to their unique optoelectronic properties. Here, a pair of chiral helical lead halides, (d-/l-pro)PbBr3·H2O (pro = proline), with centimeter-size has been successfully synthesized via integrating three types functional building units including amino acid ligand, ns2 cations, and halide anion. Their structures are composed one-dimensional {[Pb2Br6]2-}∞ chains formed by face-sharing distorted [PbBr6]4- octahedra, which separated cations crystallize into the space group P21. They present phase-matchable second-harmonic-generation (SHG) response moderate birefringence. First-principles calculations elucidate that effective SHG performances originate from synergetic contribution octahedra. This work not only enriches structural chemistry lead-based but also provides an important reference for development halides.
