Seven of the compounds crystallise in monoclinic space groups and one crystallises in an orthorhombic space group. The thermal behaviours of the materials were studied (DSC) down to liquid nitrogen temperature, and the properties of the perchlorate, hydrogen sulphate and selenate monohydrate crystals were discussed with respect to the results of high or low-temperature X-ray diffraction , IR and Raman spectroscopic studies. Quantitativemeasurements of the second harmonic generation of the powdered non-centrosymmetric samples at 1064 and 800 nmwere performed and a relative efficiency compared to KDP is presented.
