Abstract

The construction of chiral organic–inorganic hybrid materials (COIHs) based on achiral building blocks remains a huge challenge. Herein, a novel COIH [HNEt3]2n[Ag5I7]n (1) induced by achiral ammonium (HNEt3 = (CH3CH2)3NH) was synthesized, which exhibited intriguing second harmonic generation (SHG) activity and an obvious piezoelectric coefficient d33 of 5.2 pC N−1 along the polar axis.
