Abstract

The [NpO2(DPPMO2)2Cl][NpO 2Cl4] 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) 2X]2[Y] (1) (where X = Cl- and Y = [NpO 2Cl4]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. © 2010 Académie des sciences. Published by Elsevier Masson SAS. All rights reserved.
