文摘

A novel copper-substituted polyoxoanion [Cu₄(H₂O)₂(OH)₄Si₂W₁₆O₅₈]^8-(1) has been synthesized as its sodium salt, Na₈-1·26H₂O (Na-1),potassium salt, K₈-1·28H₂O(K-1), and calcium salt, Ca₄-1·48H₂O(Ca-1). Compound 1 is the first dimer of dicopper-substituted-decatungstosilicate fused in an unprecedented side-by-sidedimerization mode with a ferromagnetic coupling property.
