1,5-Diaminopentane As A Structure-Directing Agent for Zincophosphate Networks: Zn3(PO4)2(C5H14N2)2·3H2O and C5H16N2·Zn3(PO4)2(HPO4)·H2O

The crystal structures of two zincophosphate networks prepared in the presence of 1,5-diaminopentane (dap) are described. In Zn 3(PO 4) 2(C 5H 14N 2) 2·3H 2O ( 1) the dap forms Zn–N coordinate bonds to generate an unusual three-dimensional “hybrid” framework constructed from ZnO 3N, ZnO 2N 2 and PO 4 tetrahedra with three different types of elongated channels occupied by water molecules. In C 5H 16N 2·Zn 3(PO 4) 2(HPO 4)·H 2O; ( 2) the doubly-protonated H 2dap acts in a more typical way to template double layers of vertex-sharing ZnO 4, PO 4 and HPO 4 tetrahedra incorporating 10-rings and interacts with the inorganic component via N–H O hydrogen bonds.
