Synthesis and structural characterization of octanuclear indium-tungsten mixed-metal carboxylate cluster, Na-2[W3InO4(O2CEt)(8)](2)

摘要

The insoluble indium-tungsten chain cluster, Na-2[W3InO4(O2CEt)(8)](2), has been prepared from the self-assembly reaction of W(CO)(6), Na2WO4 . 2H(2)O and InCl3 in propionic anhydride at 120 degrees C. The octametallic dianion, [W3InO4(O2CEt)(8)](2)(2-), consists of the two incomplete cuboidal Units [W3O4(O2CEt)(8)](4-) which are centro-symmetrically bridged by two In3+. The In3+ ions dissociate from the trinuclear units in aqueous acidic solution. [References: 32]
