Three new beryllium phosphates, namely, H3aep·Be2(PO4)2(H2PO4)·H2O (1), H2tmdp·Be3(HPO4)3(PO4CH3)·2.25H2O (2), and H2dmpda·Be3(PO4)(HPO4)2(H2PO4) (3), were prepared under solvothermal conditions. These compounds display different open-framework structures with hcb (for 1), sql (for 2), and bnn (for 3) topologies, respectively. The formation of phosphate ester from in situ esterification reaction of phosphoric acid and methanol is noteworthy.
