Abstract: A new Co2(HPO4) 2·H2O has been hydrothermally synthesized firstly. Single crystal X-ray analysis indicates that this compound crystallizes in a hexagonal system, space group P6 5 with a=1.048 31(15) nm, b=1.048 31(15) nm, c=1.496 3(3) nm, α=90°, β=90°, γ=120°, V= 1.424 1(4) nm3, μ=3.849 mm-1, Z=6, F(000)=960, Dc=2.294 g/cm3, R=0.072 1, wR= 0.212 1, S=1.182, Δρmax=1.671×103 e·nm-3 and (Δρ)min=-1.210×103 e·nm-3. Co 1(HPO4)2·H2O is characterized by 1D 12-ring helical channels. Tetrahedral primary structure-building units of CoO4 and PO4 indicates the title compound has a zeotype framework.
