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