摘要: Two new multi-manganese-substituted polyoxotungstates K3Na10H3[{MnII(H2O)}2MnIII4(SiW6O26)(SiW9O34)2]·26H2O 1 and K5Na3[MnIII4(H2O)2(GeW9O34)2]·18H2O 2 have been successfully synthesized by the reaction of [β-XW11O36]8– (X = Si, Ge) with MnCl2 in presence potassium persulfate. Compound consisted two [B-α-SiW9O34]10– units a [B-SiW6O26] unit linked isolated tri-manganese clusters to construct double-sandwich structure. [B-α-GeW9O34]10– tetra-manganese cluster that was composed four Mn3+ ions.
