Synthesis and Crystal Structure of Open Framework Zinc-Cobalt Phosphate with Zeolite DFT Topology

The synthesis and crystal structure of Zn_(2-x)Co_x(PO₄)₂(NH₃CH₂CH₂NH₃) (x = 0.61) (ZCP-DFT) is described. ZCP-DFT is characterized by means of single-crystal and powder X-ray diffraction. Crystal data for ZCP-DFT: tetragonal, space group P4₂bc (No. 106), a = 14.7236(6) Å, b = 14.7236(6) Å, c = 8.9544(5) Å, V = 1941.17(16) Å³, Z = 8. The structure has 3-D 8-ring channel system with protonated ethylenediamine cations in the channel junctions. The framework structure type is the same as the zeolite DFT topology. The synthesis of ZCP-DFT indicates that cobalt can partially substitute the metal sties of zinc phosphate, which can lead to the modification of physical and chemical properties of the parent compounds.
