A thorium(Ⅳ) nitrate complex with phosphinoxide[-CH 2P(O)Ph 2]-substituted calixarene [L·Th^(OH 2)(NO 3) 2][Th(NO 3) 6]·CH 3CN has been prepared and characterized by elemental analysis and IR spectroscopy. Its crystal structure was determined by X-ray diffraction method. It belongs to triclinic crystal system, space group P 1, with a=1.990(7) nm, b=2.217(8) nm, c=2.890(10) nm; α=104.92(12)°, β=100.76(14)°, γ=93.13(10)°, Z=4, V=12.033(7) nm 3, R 1=0.0901, wR 2=0.1907. The complex consists of a coordination cation and a coordination anion. In the cation the thorium(Ⅳ) is coordinated to the four phosphinoxide oxygen atoms of the calixarene, four oxygen atoms from two bidentate nitrate anions and one oxygen from a water molecule forming a nine-coordinate monocapped square antiprism. In the coordination anion, the thorium(Ⅳ) is coordinated to six bidentate nitrate. In addition, an acetonitrile molecule was encapsulated in the cavity of calixarene.
