Remarkable Disparity of Second Harmonic Generation Response in Two Inorganic–Organic Hybrid Metal Thiocyanates
Colorless crystals of Cd(SCN)<sub>2</sub>(l-C<sub>5</sub>H<sub>9</sub>NO<sub>2</sub>)<sub>2</sub> (<b>1</b>) and Zn(SCN)<sub>2</sub>(l-C<sub>5</sub>H<sub>9</sub>NO<sub>2</sub>)<sub>2</sub> (<b>2</b>) were obtained by a solvent evaporation method. Compound <b>1</b> has a chainlike structure crystallized in the polar space group <i>P</i>2<sub>1</sub>, while compound <b>2</b> features a monomeric structure crystallized in the polar space group <i>C</i>2. The second harmonic generation (SHG) responses of the two metal thiocyanates are 0.5 and 3.1 times that of KH<sub>2</sub>PO<sub>4</sub>, respectively. Theoretical calculation results reveal that the strong SHG response of compound <b>2</b> stems from the cooperative effect between the linear thiocyanate groups and terminal l-proline ligands.
