Abstract

The compound [Co(NH3)6][PuO2(C2O4)2] · 3H2O was studied by single crystal X-ray diffraction. The structure contains dimeric complex anions [PuO2(C2O4)2]26− in which the coordination polyhedra of the Pu atoms are distorted pentagonal bipyramids sharing a common equatorial edge. In going from [Co(NH3)6] · [NpO2(C2O4)2] · 3H2O to [Co(NH3)6][PuO2(C2O4)2] · 3H2O, the An-O distances, both axial (in the actinyl group) and equatorial, decrease virtually isotropically.
