【摘要】 以尿素与氯化胆碱的低共熔点液体同时兼做溶剂和模板传递剂,在离子热体系下合成了InF2[PO3(OH)]2(NH4)3.采用同样的低共熔点液体在水热条件下不能得到相同的产物.产物晶体参数如下:C2/c(No.15)空间群,a=13.799(3)°A,b=5.091(2)°A,c=16.094(3)°A,β=112.942(16)°,V=1041.2(5)A°3andZ=4;R1=0.0582,wR2=0.1589.在产物结构中,In八面体与P四面体形成四员环,顶角相连形成链状结构.客体铵分子填充于链与链间的空穴中,通过氢键与骨架中的F原子,POH和P O基团作用,链与链间靠范德华力吸引进而形成层状结构.产物进一步通过粉末XR,EDX,IR,XPS和TG/DTA进行表征.更多还原

【Abstract】 A fluorinated indiumphosphate,InF₂[PO₃（OH）]₂（NH₄）₃,has been prepared under ionothermal condition using deep-eutectic solvents of choline chloride and urea as solvent and template-delivery agents.The same material can not be observed with the presence of the same deep-eutectic mixture under normal hydrothermal process.The compound crystallized in the monoclinic system,space group C2/c（No.15） with cell parameters a=13.799（3）,b=5.091（2）,c=16.094（3）,β=112.942（16）°,V=1041.2（5） ³ and Z=4;the final residual factors were R₁=0.0582 and wR₂=0.1589.The structure is built from an infinite chain composed of interconnected 4-member ring with formula of InF₂[PO₃（OH）]³-₂.The guest ammonium are hydrogen bonded to the F atoms located in two outmost vertexes of indium octahedral and terminal P-OH and PO groups in the chain respectively.The integrated framework is formed by van der Waals forces holding the chains together as extensive H bond array exists in the compound.The further characterizations of the compound have been performed by X-ray powder diffraction,EDX,IR,XPS and TG/DTA analyses.更多还原
