英文摘要Ionothermal synthesis (ITS) as a new synthesis method of microporous materials has attracted more and more attention in recent years. It has many advantages comparing with hydrothermal and solvothermal methods1. First of all, the reaction can take place at ambient pressure, eliminating the safety concerns. Secondly, Ionic Liquids (ILs) play both solvent and structure-directing agent roles, removing the competition interaction between template-framework and solvent-framework, and leading potentially to a new framework. Up to now, most studies of ITS are concentrated on [emim]Br (emim = 1-ethyl-3-methylimidazolium) and the synthesis of aluminophosphates2. In this work, we tried to use BF4- based dialkylimidazolium ILs to synthesize new transition metal borophosphate. Unexpectedly, a known phosphate Co7H4(PO4)63 was obtained. Typically, [bmim]BF4 (bmim = 1-butyl-3-methylimidazolium), H3PO4 and Co(OAc)2•4H2O with a molar ratio of 9 : 1 : 1 were charged into a 15 mL Teflon-lined stainless steel autoclave and heated under 180 ℃ for 5 days. Stick-like blue single crystals were received as final product. The crystal structure of Co7H4(PO4)6, as shown in Fig.1, was determined by the single crystal X-ray diffraction method. Co7H4(PO4)6 crystallizes in the space group P-1 (No.2), with cell parameters of a = 6.471(3) Å, b = 7.881(3) Å, c = 9.488(4) Å, α = 104.288(6)°, β = 109.062(5)° and γ = 101.345(5)°. The effects of different anions were studied and it was found that when [bmim]Br or [bmim]Cl was used, under the same condition, even no solid products were formed. This shows that halogen anions have a negative effect on the process of crystallization. In conclusion, this work shows that the synthesis of metal phosphates by using ITS method is possible after selecting of the right ionic liquid as solvent.
