Abstract: By red-ox reconstructing (ROR) method, we synthesized and analyzed the het eropoly compound K3Na[Se2Mo5O21]·2H2O with Strandberg-type structure.The crystals are the polyanion, five MoO6octahedra are connected by edge sharing, and the two octahedra at the two ends are connected by conner sharing to complete the Mo5ring, the two SeNO3trigonal pyramids are attached to the ring from above and below the ring.

Key words: Se,Mo, Heteropolyanion, Crystal structure
