|Abstract:||The new compound SrNp(PO4)2 (orthorhombic Cmca) has been synthesized by solid state reaction and studied by Rietveld analysis. Though chemically and structurally related to cheralite CaTh(PO4)2, it shows alternate layers of SrO10 and NpO8 polyhedra instead of a disordered array of MO9 units. This unknown structural model allows explaining the narrow limits of the cheralite domain in terms of cations size and suggests that transuranium-loaded compounds could also be ordered derivates of the archetype. The validity of thorium-designed models for approaching transuranian structural chemistry is discussed|
