N2 - The crystal structures of two zincophosphate networks prepared in the presence of 1,5-diaminopentane (dap) are described. In Zn3(PO4)2(C5H14N2)2•3H2O (1) the dap forms Zn-N coordinate bonds to generate an unusual three-dimensional "hybrid" framework constructed from ZnO3N, ZnO2N2 and PO4 tetrahedra with three different types of elongated channels occupied by water molecules. In C5H16N2•Zn3(PO4)2(HPO4)•H2O; (2) the doubly-protonated H2dap acts in a more typical way to template double layers of vertex-sharing ZnO4, PO4 and HPO4 tetrahedra incorporating 10-rings and interacts with the inorganic component via N-H O hydrogen bonds. Crystal data: 1 (C10H34N4O11P2Zn3), Mr = 644.46, monoclinic, C2 (No. 4), Z = 4, a = 25.302 (7) Å, b = 4.9327 (13) Å, c = 19.808 (6) Å, b = 107.377 (8)°, V = 2359.4 (12) Å3, R(F) = 0.054, wR(F2) = 0.139. 2 (C5H19N2O13P3Zn3), Mr = 604.24, monoclinic, P21/c (No. 14), Z = 4, a= 11.3275 (15) Å, b = 8.3235 (11) Å, c = 18.588 (2) Å, b = 96.979 (3)°, V = 1739.6 (4) Å3, R(F) = 0.056, wR(F2) = 0.119.
