Crystallizes in the chiral space group P2₁2₁2₁ at room temperature
Reversible transition from SHG-on to SHG-off upon heating and cooling
Space group changes from noncentrosymmetric to centrosymmetric across the phase transition
Incorporating rare-earth elements as hybrid B-site cations imparts exceptional fluorescence properties
