摘要: A new acentric galloborate (GBO) [H2dab][GaB5O10] (1, 1,4-dab: 1,4-diaminobutane) has been synthesized under solvothermal conditions. The alternation of 4,4-connected GaO4 and B5O10 cluster build up the 3D [GaB5O10]n2n uninodal framework, which contains three pairs of helical channels with 8-member ring (MR) and 7-MR apertures, respectively. Compound 1 exhibits a moderate second harmonic generation (SHG) response of 1.8 times that of KH2PO4 (KDP), indicating its potential application in UV regions. The acentric uninodal framework in compound 1 represents a new type of zeolitic framework in the GBOs’ family.
