Abstract:
The crystal structure of the anionic zinc-[amino-(iminio)meth-yl]phospho-nate 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]} . The building unit of the coordination polymer comprises a divalent Zn2+ cation (site symmetry ..) and three [amino(iminio)meth-yl]phospho-nate mono-anionic ligands (point group symmetry m). The AIMP ligand exists in a zwitterionic form with a total charge -1 as the phospho-nate is fully deprotonated (-PO3 2-), while the amino-(iminio)methyl moiety is protonated (H2N-C-NH2 +).
