Despite a high similarity of the molecular structures, all three materials featured unrelated non-centrosymmetric crystallization behavior. Inspection of the nonlinear optical activity of single crystalline powders revealed an extraordinarily efficient second harmonic generation of one of the materials with a 1200-fold increased second harmonic response compared to potassium dihydrogen phosphate.
