Abstract A new SHG material, namely, Pb 2 (BO 3 )(NO 3 ), which contains parallel π‐conjugated nitrate and borate anions, was obtained through a facile hydrothermal reaction by using Pb(NO 3 ) 2 and Mg(BO 2 ) 2 ⋅H 2 O as starting materials. Its structure contains honeycomb [Pb 2 (BO 3 )] ∞ layers with noncoordination [NO 3 ] − anions located at the interlayer space. Pb 2 (BO 3 )(NO 3 ) 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 Pb 2 (BO 3 )(NO 3 ) arises from the synergistic effect of the stereoactive lone pairs on Pb 2+ cations and parallel alignment of π‐conjugated BO 3 and NO 3 units. Based on its unique properties, Pb 2 (BO 3 )(NO 3 ) may have great potential as a high performance NLO material in photonic applications.
