Abstract

Single crystals of [PuO2(NO3)2(TPPO)2] (TPPO = OPPh3) isostructural to the related compounds of uranyl and neptunyl were isolated, and the structure of this complex was determined. Contrary to the complexes [AnO2(TPPO)4](ClO4)2 studied previously, the interatomic distances and volumes of coordination polyhedra of An in these compounds somewhat decrease in the series U-Np-Pu. This difference was attributed to a change in the number of TPPO ligands in the compounds and weakening of their interaction with oxygen atoms of the AnO 2+2 groups in passing from [AnO2(TPPO)2](ClO4)2 to [AnO2(No3)2(TPPO)2].
