Abstract: Three new hybrid crystals of 2-aminophenol-HClO4 (2-AP-HClO4,1), 3-aminophenol-HClO4 (3-AP-HClO4, 2) and 4-aminophenol-HClO4 (4-AP-HClO4, 3) were obtained and their crystal structures determined. The 1 crystallises in centrosymmetric space group C2/c of monoclinic system while the other two (2 and 3) crystallise in the non-centro symmetric space groupP21 andP212121, respectively. The oppositely charged units of the crystals, i.e. positively charged 2-APHþ, 3-APHþ and 4-APHþ and ClO4 , interact viaweak Nþ–H/O and O– H/O hydrogen bonds forming 3D-supramolecular network. Relative to KDP the SHG efficiencies are 0.62 for 2 and 0.33 for 3, measured at 1064 nm using the Kurtz–Perry method.
