A series of open-framework aluminoborates (ABOs), namely, [Zn-2(en)(5)][Al2B10O20] (1), [Zn(en)(dien)][AlB5O10] (2), [Zn(en)(3)][AlB7O12 (OH)(2)] (3), [Zn(en)(2)][AlB5O10] (4), K-7{AlO0.5[BO2(OH)]Zn@[B12O21(OH)(3)]}H2O (5) (en=ethylenediamine, dien=diethylenetriamine) have been made under mild solvothermal conditions and characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, IR and UV/Vis spectroscopy, thermogravimetric analysis, and nonlinear optical determination. They were classified as two types: Compounds 1-4 contain intersecting channels and exhibit various 4-connected nets built by AlO4 tetrahedra and oxo boron clusters, zinc-amine complexes act as the templates (1-3) or directly bond to the walls of the ABO (4); compound 5 exhibits a double-layer structure made by nanosized [BO2(OH)]Zn@[B12O21(OH)(3)] ({BZn@B-12}) clusters with Al2O7 dimers, the channels are within the layer. The second harmonic generation (SHG) measurement shows that the SHG responses of 1-3 are about 2.5, 1.6, and 0.5 times that of KH2PO4. Compounds 1-2 are typeI phase-matchable materials. UV/Vis spectroscopy indicates that compounds 1-5 are wide-band-gap semiconductors.
