| Abstract: In this paper, the extraction mechanism of Ho3+ from ROH-H2O mixed solutions by 1-phenyl-3-methyl-4-benzoyl-pyazolone-5 in chloroform has been investigated. The solid extraction complex Ho(PMBP)3·2H2O has been prepared and characterized by X-ray crystrallography and IR spectroscopic measurement. The crystal is monoclinic with space group P21/n, a=1.5035(4) nm，b=1.4710(2)nm, c=2.4391(4)nm, β=101.407(1)°, Z=4, V=5.28775 nm3, Dcalc=1.415 g/cm3. Each holmium ion is coordinated by 8 oxygen atoms, contributed by three PMBP anions, and two H2O molecules, arranged at the vertices of two square prisms with the same apical position and rotated 45° comparatively. |
