Abstract

A high second harmonic generation response is demonstrated by a Pb₆O₅(NO₃)₂ lead oxynitrate whose identity was verified upon reinvestigation of the PbO-Pb(NO₃)₂ system. Its crystal structure exhibits a unique cationic [Pb₆O₅]²⁺ framework hosting orientationally ordered NO₃^- triangles in the channels. Easy preparation and high thermal stability (until ∼500 °C in air) suggest it to be a new promising NLO material.
