Keywords: | Dicarboxylates; Hydrogen bonds; Molecular crystals; Supramolecular assemblies; Second-harmonic generation; Nonlinear optical materials | Issue Date: | 2006 | Citation: | Journal of Solid State Chemistry. 179:8 (2006) 2521-2528 | Abstract: | A new nonlinear optical material, l-histidinium hydrogen malate, has been synthesized. The crystal structure was determined at 90 K by single-crystal X-ray diffraction in order to analyze its supramolecular structure. A new building block type has been found. The malate anions form head-to-side infinite chains parallel to [100], via O-H...O interactions, instead of the usual head-to-tail infinite chains found in other hydrogen malate salts. The l-histidine cations form chains parallel to [100] via N-H...O hydrogen bonds, with cations of adjacent chains in anti-parallel way. The compound shows a good optical second-harmonic generation capability with an effective second-order susceptibility estimated to be 0.70 of that for potassium dihydrogen phosphate. | URI: | https://hdl.handle.net/10316/4396 | DOI: | 10.1016/j.jssc.2006.05.006 | Rights: | openAccess |
