The new zincophosphate [Zn-3(HPO4)(4)](NMe4)(2), I, has been synthesized hydrothermally, and the crystal structure was determined by single-crystal X-ray diffraction. Corner-sharing ZnO4 and PO3 (OH) tetrahedra form zigzag ladder chains of edge-sharing 4-membered rings. These chains link into the anionic host framework that, formally, generates a three-dimensional system of intersecting channels bound by 16-membered rings, in which tetramethylammonium cations reside. However, the channels are partly blocked by hydrogen bonds in [H-O(P)](4) groupings. Formal substitution of the four H atoms in each grouping by a tetravalent cation results in a fully four-connected network of equal charge and novel topology that generates gismondine-type [4(6)8(4)] cavities at the intersections of 8-membered ring channels. I was further studied by variable-temperature powder X-ray diffraction, thermogravimetry, and FT-IR spectroscopy.
