A series of open‐framework aluminoborates (ABOs) [M(dien) 2 ][AlB 6 O 11 (OH)] (M=Co ( I a ), Ni ( I b ), Cd ( I c ), Zn ( I d ); dien=diethylenetriamine) and [M(en) 3 ][AlB 7 O 12 (OH) 2 ] ⋅ (H 2 O) 0.25 (M=Co ( II a ), Ni ( II b ); 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, single‐crystal X‐ray diffraction, and nonlinear optical determination. These compounds were classified as two structural types: Type I ( I a – d ) contains AlO 4 tetrahedra and B 6 O 11 (OH) clusters, which link to form a new 3D framework with 7‐/9‐ring helical channels and large 13‐ring channels; whereas type II ( II a , b ) is composed of AlO 4 tetrahedra, chainlike B 4 O 6 (OH) 2 tetramer, and crablike B 6 O 12 clusters, which interconnect to form other new 3D frameworks with 8‐ring 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). I c , d present good second harmonic generation (SHG) properties. UV/Vis spectral investigation indicates that I a – d and II a , b are wide‐band‐gap semiconductors.
