Abstract
Abstract 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) A, b=5.1036 (5) A, c=18.100 (2) A, β=94.491 (2)°, V=2189.0 (5) A3, Z=4, R(F)=0.047, Rw(F2)=0.121 (2322 reflections, 168 parameters).
