| Abstract: | A novel 3D aluminoborate with [Zn(H2O)4]2+ cationic complexes as structure-directing agents (SDAs), namely, [Zn(H2O)4][Al(B5O10)]·0.5(H2O) (1), has been solvothermally prepared and characterized by IR spectroscopy, UV–vis reflection spectroscopy, thermogravimetric (TG) analyses, powder and single crystal X-ray diffraction, respectively. The alternative linkage of AlO4 tetrahedra and B5O10 units produces an open-framework aluminoborate with helical 6- and 8-membered ring (MR) channels, as well as large odd 11-MR channels. The [Zn(H2O)4]2+ templates, generated in situ from solvothermal conditions, are orderly located in the center of the 11-MR channels. The second-harmonic generation (SHG) measurement indicates that 1 exhibits about 0.5 times that of KDP standard (K2HPO4). |
