Two three-dimensional (3D) zeolitic open-framework aluminoborates (ABOs) [Zn(ma)(en)][AlBO] (1) and [Zn(ma)(en)][AlBO(OH)] (2) (ma = methylamine, en = ethylenediamine) were successfully made under solvothermal conditions, which represent the first examples using similar metal complex (MC) with mixed amines as the structure-directing agents in ABOs. Notice that the central atom in the MC is coordinated by mixed amines is uncommon. However, they exhibit distinctly different structures: 1 crystallizes in a centrosymmetric [Al(BO)] zeolitic framework built by pentaborate (BO) clusters and AlO tetrahedra, exhibiting a 4-connected cag topology, while 2 contains hexaborate (BO(OH)) clusters and AlO groups, further alternately joined to form a noncentrosymmetric [AlBO(OH)] zeolitic framework with 7-/9-, 8-/10-ring helical channels and large 13-ring channels, showing a dia topology. Nonlinear optical (NLO) determination showed that 2 exhibits good second-harmonic generation response of ∼1.9 × KHPO and is phase-matchable, combining the short UV cutoff edge, making 2 a potential UV NLO material.

A series of alumino/galloborates, including (H3APEA)6[Al-B5O10]9·12H2O (1, APEA = N,N′-bis(3-aminopropyl)ethylenedi-amine), (HDETA)2(H2DETA)2[AlB5O10]3 (2, DETA = diethylenetriamine), and (H2EDAP)[GaB5O10]·H2O (3, EDAP = N-ethyl-diaminopropane), was solvothermally synthesized and characterized in solid-state by powder X-ray diffraction, Fourier transform infrared spectroscopy, UV–vis spectroscopy, and single-crystal X-ray diffraction. All of them feature the [MB5O10] n 2n– (M = Al or Ga) frameworks, charge-balanced by the long chain-like amine cations. Three frameworks exhibit different interlinkage modes of {MB5O10} layers, resulting in channels varying in size and shape. The flexibility of long chain-like amine cations as well as their significant structure-directing functions in forming these crystalline products is also discussed in detail. Powder second-harmonic generation measurements showed that all three compounds present a nonlinear optical property, and compound 2 exhibits type I phase-matchable optical nonlinearity.

“…Limited ABOs were successfully made with definite structures owing to the difficulties in obtaining single crystals for structural determination. 22–25 Since 2009, we firstly proposed the use of aluminium isopropoxide (Al( i -PrO) 3 ) as the Al source, replacing the traditional inorganic Al sources to synthesize ABOs under hydro(solvo)thermal conditions, 5 large amounts of ABOs were made, which not only expand the ABO open framework family with definite structures, but also increase the possibility of acentric structures through the synergistic effects of chiral AlO 4 group and acentric oxoboron clusters. 26–29 As part of our ongoing work, we continue to expand our research focus to GBOs with the similar Ga source of gallium isopropoxide (Ga( i -PrO) 3 ) and make a series of them with novel structures.…”
