Inorganic oxoanions, compounds containing

The purpose of this chapter is to address the role of heavy oxoanions containing a chemically inert, but stereochemically active, lone-pair of electrons on the structures of purely inorganic actinide compounds. This work is not intended to be a comprehensive survey of all compounds that fall into this class, but rather its goal is to highlight key compounds with atypical structures where the influence of the lone-pair of electrons can be ascertained, if only in part. 

Many complex structures can be formed with various Mo and V oxoanions and organic cations. The crystalline compound [Me2NH2]K4VioOio(H20)2(OH)2(P04)7-4H20 contains a remarkable inorganic double helix consisting of two intertwined but independent spirals of linked O and V atoms [106].
