摘要：

The solid acid of the first protonated zincoborophosphate, (H 3O)Zn(H 2O) 2BP 2O 8·H 2O (1), was soventothermally synthesized by the reaction of Zn(NO 3) 2·6H 2O and H 3BO 3 with H 3PO 4 in a mixed solvent, and structurally characterized by single-crystal X-ray diffraction analysis. It crystallizes in the hexagonal P6 122, a=0.9604(4) nm, c=1.5297(6) nm, V=1.2218(8) nm 3, D c=2.921 g/cm 3, Z=6, F(000)=1080, μ=3.495 mm -1. The structure features that the tetrahedra-tetrahedra helices interconnected by octahedra and strong hydrogen bond interactions form a three-dimensional framework. The protonated water molecules are located at unique positions. Other characterizations by IR and thermal analysis are also described.
