Two pyridine dipyrrolide neptunium(IV) complexes, (PDP)NpCl(THF) and Np(PDP), where (PDP) is the doubly deprotonated form of 2,6-bis(5-(2,4,6-trimethylphenyl)-3-phenyl-1-pyrrol-2-yl)pyridine, have been prepared. Characterization of the complexes has been performed through a combination of solid- and solution-state methods, including single-crystal X-ray diffraction and electronic absorption and nuclear magnetic resonance spectroscopies. Collectively, these data confirm the formation of the mono- and bis-ligated species. Electrochemistry of a series of bis-ligated actinide complexes, An(PDP) (An = Th, U, Np), is presented.
已制备出两种吡啶二吡咯镎（IV）配合物，即（PDP）NpCl（THF）和Np（PDP），其中（PDP）是2,6 - 双（5 - （2,4,6 - 三甲基苯基） - 3 - 苯基 - 1 - 吡咯 - 2 - 基）吡啶的双去质子化形式。通过固态和溶液态方法相结合对配合物进行了表征，包括单晶X射线衍射、电子吸收光谱和核磁共振光谱。总体而言，这些数据证实了单配位和双配位物种的形成。还介绍了一系列双配位锕系元素配合物An（PDP）（An = Th、U、Np）的电化学性质。
