Synthesis and Properties of Neptunium(V) Propionates

Radiochemistry Aims and scope

Abstract

From propionate-containing solutions of Np(V), the crystalline compounds NpO2OOCC2H5·nH2O with n = 1 or 2 and M(NpO2)2(OOCC2H5)3·H2O with M = NH4 or Cs were separated. Their X-ray powder patterns were recorded and behavior at heating was studied. The IR and electronic absorption spectra suggest that, in these compounds, the NpO2 + ions are coordinated with each other to form cation-cation bonds involving all “yl” oxygen atoms.
