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.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 templatedelivery agents. The same material can not be observed with the presence of the same deep-eutectie 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）A^°, b = 5.091（2）A^°, c = 16.094（3）A^°,β= 112. 942（16） °, V = 1041.2 （5） A^°^3 and Z = 4 ; the final residual faetors were R1 = 0.0582 and wR2 = 0.1589. The strueture is built from an infinite chain composed of interconnected 4-member ring with formula of InF2 [PO3 （OH）]2^3- . The guest ammonium are hydrogen bonded to the F atoms loeated 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.
