X-Ray diffraction results are reported for the above complexes, together with details of conditions necessary for formation of the α and β phases of the tetrakis(pentane-2,4-dionato)actinoid(IV) complexes. Solid-state spectral results (0·5–2·2 µm) are provided for β-[Pa(pd)4], β-[U(pd)4], β-[Pu(pd)4], and [Pu(pd)3] together with i.r. results for these complexes, those of
由五氯化pro与戊烷-2,4-二酮(Hpd)在二氯甲烷中的反应制得三氯双(戊烷-2,4-二价)act(V),[PaCl 3(pd)2 ]。 Pa(dppd)4 ]和[Pa(dp)4 ](dppd = 1,3-二苯基丙烷-1,3-dionato)来自涉及适当螯合物的al盐和[Et 4 N] 2 [PaCl 6 ]的反应和无水非水溶剂中分别加入PaCl 4和PaCl 4。在Hpd存在下,在溶剂(例如苯和乙醇)中氧化[Pu(pd)3 ]会生成[Pu(pd)4 ]。尝试准备[Am(pd)4]和类型为M [Th(pd)5 ](M =单价阳离子)的络合物均未成功。报道了上述配合物的X射线衍射结果,以及形成四(戊烷-2,4-二氢呋喃基)肌动蛋白(IV)配合物的α和β相所必需的条件的细节。提供了β-[Pa(pd)4 ],β-[U(pd)4 ],β-[Pu(pd)4 ]和[[ Pu(pd)3 ]以及ir结果,这些配合物类型为[M(pd)4
