The title compound, (C2H10N2)3(C2H9N2)2[Mo5(HPO4)2O15]·10H2O, was prepared under hydrothermal conditions at pH 5.0. The structure contains mono- and diprotonated ethylenediamine cations, [Mo5O15(HPO4)2]4− anions and uncoordinated water molecules. The [Mo5O15(HPO4)2]4− heteropolyoxometallate anion is made up of five MoO6 octahedra sharing an edge and forming a ring, which is closed by common corners of the terminal MoO6 octahedron. The ring is topped on both sides by two slightly distorted PO4 tetrahedra, sharing three corners with three MoO6 octahedra. The terminal oxygen atoms of the PO4 units are protonated. Together with the anions, the water molecules and the ethylenediammonium cations are involved in N—H...O and O—H...O hydrogen bonding, forming a three-dimensional supramolecular network
