An open-framework zinc-cobalt phosphate CoZnPO4-V with 16-ring extra-large-pore channels has been obtained in the presence of chain-type polyamines as the structure directing agent (SDA). Its large single crystal suited for structure refinement has been prepared with the assistance of small organic amines. Single-crystal X-ray diffraction analysis has shown that CoZnPO4-V is a novel metal phosphate. It crystallizes in monoclinic space group P21/c (No. 14), with a = 31.936(3) , b = 8.3775(7) , c = 15.7874(13) , α = γ = 90°, β = 97.0530(10)°, V = 4191.8(6) 3, and Z = 4 with R1 = 0.0455,wR2 = 0.0869. Its three-dimensional framework can be considered as stacking from two-dimensional nets and one-dimensional units as linkers. Between the stacking nets and linkers are located extra-large channels with 16-ring apertures.
