| Abstract: | The complex,{Pr2(B-ala)6(H2O)4](ClO4)6.H2O}n(β-alanine=β-alanine),was synthesized in an aqueous solution with a PH value of 4. Its crystal structure was determined by X-ray diffraction method. The crystal istriclinic with space group of Pi. The cell parameters are a = 9.388(1)A, b= 12.906(2)1,c=21.690(4)A, a = 76.90(1),β=81.04(1)°,γ= 83.23(1)°,Z=2,Mr=1503.18,Dc=1.982g/cm3.The structure of the complex can be viewed as a one-dimensional infinite chain. The Pr( III) ion is nine-coordinated with a geometry of distorted mono-capped square antiprism. |
