Abstract

The [NpO2(DPPMO2)(2)Cl][NPO2Cl4] complex (where DPPMO2= bis(diphenylphosphino)-methanedioxide) contains the linear neptunyl group, {NpO2}(2+), with two bidentate P=O donor ligands Coordinating anion Cl- fills the fifth equatorial coordination site yielding a complex of general formula [NpO2(DPPMO2)(2)X](2)[Y] (1) (where X = Cl- and Y = [NPO2Cl4](2-). Reaction between our newly prepared neptunium starting material [NpO2Cl2(thf)(n) and phosphinimine ligand produced crystals of [Ph3PNH2](2)[NpO2Cl4] (2). Compounds 1 and 2 have been structurally characterised (C) 2010 Academic des sciences.
