The title compound, catena-poly[[N-methylpropane-1,3-diaminium [μ-phosphato-(μ-hydrogen phosphato)(μ-dihydrogen phosphato) dizincate(II)]], {(C4H14N2)[Zn 2(PO4)(H-PO4)(H2PO 4)]}n, consists of macroanionic [Zn2(PO 4)(HPO4)-(H2PO4)]2- layers and intercalated (C4H12N2)2- cations. The layers are built up from ZnO4 and PO4/ HPO4/H2PO4 tetrahedra that result in small channels of approximate diameter 3.7 Å within the layers. Framework-to-framework O-H⋯O and template-to-framework N-H⋯O hydrogen bonds are important in stabilizing the structure. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
