摘要：

The non-metal cation pentaborate(1-) salt [p-H2NC6H4CH2NH3][B5O6(OH)(4)]center dot 1/2H(2)O (1) was synthesised from B(OH)(3) and p-H2NC6H4CH2NH2 and crystallized from aqueous solution. Compound 1 was characterized by thermal (TGA/DSC), spectroscopic (IR, NMR) and single-crystal X-ray diffraction methods and it was found to crystallize in the non-centrosymmetric point group P2(1). Powder SHG measurements on 1 and some related alkylammonium pentaborate salts, [NH3CMe2(CH2OH)][B5O6(OH)(4)], [NH3CMe(CH2OH)(2)][B5O6(OH)(4)] and [NH3CHMeCH2OH][B5O6(OH)(4)], a substituted imidazolium salt, [1,2,3-Me3C3H2N2][B5O6(OH)(4)], a substituted piperidinium salt, [(CH2)(5)NH(CH2CH2OH)][B5O6(OH)(4)], and a substituted pyrrolidinium salt, [S-(+)-2-(HOCH2)C4H7NH2][B5O6(OH)(4)], were determined. Compound 1 and all compounds, except [1,2,3-Me3C3H2N2][B5O6(OH)(4)], showed some weak SHG activity with SHG efficiencies of 0.1-0.2 relative to that of KH2PO4 (KDP).
