The solution-mediated synthesis and single crystal structure of (CN3H6)2 · Zn4H5(PO4)5, a new guanidinium zinc phosphate, are described. The use of high-intensity synchrotron radiation was necessary to determine the correct unit cell for this phase. Unlike the previously described one-dimensional or three-dimensional guanidinium zinc phosphates, this material has a strongly layered nature. Vertex-linked ZnO4, HPO4, and H2PO4 building units self-assemble into complex sheets containing polyhedral 3-rings, 4-rings, and 8-rings. The intersheet guanidinium cations provide charge compensation and interact with the layers via N-H ⋯ O hydrogen bonds. Crystal data: (CN3H6)2 · Zn4H5 (PO4)5, Mr = 861.57, monoclinic, space group I2/a (No. 15), a = 23.770 (2) Å, b = 5.1036 (5) Å, c = 18.100 (2) Å, β = 94.491 (2)○, V = 2189.0 (5) Å3, Z = 4, R(F) = 0.047, Rw(F2) = 0.121 (2322 reflections, 168 parameters). © 1999 Academic Press.
