Abstract: The compounds [M4(H2O)2(AsW9O34)2]10-(M=CuⅡ,CoⅡ,MnⅡ, NiⅡ, ZnⅡ) were synthesized and characterized by IR, UV, elemental analysis and magnetic measurements.These compounds are isostructural to the Pderivatives and comprise a rhomb-like M4O16 group encapsulated between two fragments of the trivacant Keggin polyanion [AsW9O34]9-.The crystal structures of the MnⅡ and CuⅡ derivatives were compared with that of the Pderivatives.The MnⅡ derivative exhibits antiferromagnetic Mn-Mn exchange interactions and S=0 ground state.

Key words: Sandwich-type tungstoarsenates, Synthesis, Structure, Magnetic property
