Five new mixed-valence Np/An molybdates of the composition [C(NH)][(NpO)(NpO)(MoO)(HO)]·HO (), [C(NH)][(NpO)(NpO)(MoO)(HO)]·3HO (), Na[(NpO)(PuO)(MoO)(HO)]·HO (), Na[(NpO)(UO)(MoO)]·13HO (), and LiNa[(NpO)(NpO)(MoO)(HO)]·4HO () have been synthesized and structurally characterized. The coordination polyhedra of the Np and An atoms in compounds - are pentagonal bipyramids. The basis of structures - is anionic layers of the composition [(NpO)(AnO)(MoO)(HO)]. Three crystallographically independent molybdate ions are tridentate-bridging ligands. The water molecule, which is a part of the anion layer, is coordinated to the Np atom. The anionic layers in complexes and have the same structure, different from . The basis of structure is anionic layers of the composition [(NpO)(UO)(MoO)], the structure of which differs from the structure of anionic layers in -. Complex has a three-dimensional (3D) structure. The spectra of all compounds in the UV-visible and IR ranges were measured and analyzed.
