N2 - A series of open-framework aluminoborates (ABOs) [M(dien) 2][AlB6O11(OH)] (M = Co (Ia), Ni (Ib), Cd (Ic), Zn (Id); dien = diethylenetriamine) and [M(en)3][AlB 7O12(OH)2]· (H2O) 0.25 (M = Co (IIa), Ni (IIb); en = ethylenediamine) have been made under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, UV/Vis and fluorescence spectroscopy, powder X-ray diffraction, singlecrystal X-ray diffraction, and nonlinear optical determination. These compounds were classified as two structural types: Type I (Ia-d) contains AlO4 tetrahedra and B6O11(OH) clusters, which link to form a new 3D framework with 7-/9-ring helical channels and large 13ring channels; whereas type II (IIa,b) is composed of AlO 4 tetrahedra, chain-like B4O6(OH)2 tetramer, and crablike B6O12 clusters, which interconnect to form other new 3D frameworks with 8ring helical channels, rare 16-ring double-helical channels, and larger odd 15-ring channels. These compounds represent the first examples of 3D ABOs templated by transition-metal complexes (TMCs). Ic, d present good second harmonic generation (SHG) properties. UV/Vis spectral investigation indicates that Ia-d and IIa,b are wide-band-gap semiconductors.
