The crystal structure of the anionic zinc–[amino(iminio)methyl]phosphonate one-dimensional coordination polymer, Zn-AIMP, is reported; the negative charge is balanced by an oxidanium cation (H3O+) to give the composition {(H3O)[Zn(CH4N2PO3)3]}n. The building unit of the coordination polymer comprises a divalent Zn2+ cation (site symmetry \overline3..) and three [amino(iminio)methyl]phosphonate mono-anionic ligands (point group symmetry m). The AIMP ligand exists in a zwitterionic form with a total charge −1 as the phosphonate is fully deprotonated (–PO32−), while the amino(iminio)methyl moiety is protonated (H2N—C—NH2+).
