Abstract:

A cerium sulfate hydrate, [C4N2H12]3[Ce2(SO4)6(H2O)2]·H2O, was synthesized via the hydrothermal method with piperazine as a template and characterized by single-crystal X-ray diffraction. The compound crystallizes in monoclinic system, space group P21/c with cell parameters a=0.66335(10) nm, b=2.8088(4) nm, c=1.02212(15) nm, β=96.160(2)°, final R indices [I>2σ(I)], R1=0.0466 and wR2=0.1226. The compound exhibits a corrugated layer structure, which is constructed from inorganic anionic sheets of cerium sulfates with diprotonated piperazine cations and water molecules locating between the layers. An eight-membered ring is created in the layer with a diprotonated piperazine molecule locating in it. The thermal behavior of the compound was also examined.
