摘要 The title complex (h5-C5H5)Pr(acac)2(m3-OH)]24THF was prepared by the reaction of Cp3Pr with equimolar bis(acetylacetone)ethylenediamine (H2acac) in THF, and its crystal structure was characterized by X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n with a =13.286(2), b =13.121(2), c = 23.95(1) ? = 93.50(2)? V = 4167(1) ?, Z = 2, C74H116O14N8Pr4, Mr = 1905.41, Dc = 1.523 g/cm3, F(000) = 1940 and ?MoK? = 23.51 cm-1 (?= 0.7107 ?. The final R and Rw are 0.033 and 0.046, respectively with 5968 observed reflections. It is a partially hydrolytic product, containing hydroxyl bridge in a m3-fashion. The molecular structure shows that there exist two symmetrical units collected via two hydroxide groups and two oxygen atoms from the Schiff base ligands. In each unit, there are two praseodymium atoms with different coordination.
