Four beryllium hydrogen phosphates, Be 2 (Hea)(PO 4 )(HPO 4 ) ( 1 ), Him · Be 3 (OH)(HPO 4 ) 3 ( 2a ), Hpy · Be 3 (OH)(HPO 4 ) 3 ( 2b ), and Hma · Be 1.5 (HPO 4 ) 2 · 0.5H 2 O ( 3 ) in which ea = ethanolamine, im = imidazole, py = pyridine, and ma = methylamine, were synthesized under solvothermal conditions. All compounds have open‐framework structures with (3,4)‐connected networks. Compound 1 features a neutral inorganic–organic hybrid framework with an interrupted zeolitic GIS topology. The dual role of the amine molecules as charge‐balancing agents and coordinating agents to the beryllium atoms is noteworthy. Compounds 2a and 2b are isostructural, and they have an AFI‐related framework with elliptical 12‐ring channels. Compound 3 has a 3D structure with 4.8 2 layers pillared by corner‐sharing four‐ring chains. It represents the first example of an open‐framework beryllium hydrogen phosphate with 16‐ring channels.
