Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A new SHG material, namely, Pb₂(BO₃)(NO₃), which contains parallel π‐conjugated nitrate and borate anions, was obtained through a facile hydrothermal reaction by using Pb(NO₃)₂ and Mg(BO₂)₂⋅H₂O as starting materials. Its structure contains honeycomb [Pb₂(BO₃)]_∞ layers with noncoordination [NO₃]⁻ anions located at the interlayer space. Pb₂(BO₃)(NO₃) shows a remarkable strong SHG response of approximately 9.0 times that of potassium dihydrogen phosphate (KDP) and the material is also phase‐matchable. The large SHG coefficient of Pb₂(BO₃)(NO₃) arises from the synergistic effect of the stereoactive lone pairs on Pb²⁺ cations and parallel alignment of π‐conjugated BO₃ and NO₃ units. Based on its unique properties, Pb₂(BO₃)(NO₃) may have great potential as a high performance NLO material in photonic applications.</p> </abstract>
