Mixed-valent neptunium oligomer complexes based on cation–cation interactions

Author affiliations

Abstract

Mixed-valent tri- and tetranuclear complexes of neptunium, [{NpIVCl4}{NpVO2Cl(THF)3}2]·THF and [{NpIVCl3}{NpVO22-Cl)(THF)2}33-Cl}] (THF = tetrahydrofuran), were synthesised and characterised. Both the complexes are formed via the cation–cation interactions between the Np(IV) centre and the axial oxygens of the neptunyl(V) unit (i.e. trans-dioxo NpO2+ cation), demonstrating the potential of cation–cation interactions for further exploring the oligomer/cluster chemistry of actinides.
