Form-controlled synthesis of a polymorphic nonlinear optical crystal CsMgPO4·6H2O†
A facile solution method for the form-controlled synthesis of CsMgPO4·6H2O is reported in this work and the key factor was determined to be the pH value of the solution used. A pure hexagonal phase (P63mc) was obtained at a pH range of 6.9–8.0, whereas a cubic phase (F3m) was obtained at 9.5–11.3. Compared with the cubic phase, the hexagonal phase of CsMgPO4·6H2O possessed a stronger second harmonic generation response of 0.82 pm V−1 due to the distortion of the PO4 motif from a regular tetrahedron. The form-controlled synthesis mechanism was identified with the aid of infrared spectroscopy: the protonation process reduced the symmetry of the PO4 motif when the solution pH decreased, resulting in the crystallization of the hexagonal phase of CsMgPO4·6H2O with the distorted PO4 tetrahedron at a lower pH range.
