L. Xu et al., SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF OCTANUCLEAR INDIUM-TUNGSTEN MIXED-METAL CARBOXYLATE CLUSTER, NA-2[W3INO4(O2CET)(8)](2), Chemistry Letters, (1), 1998, pp. 35-36
The insoluble indium-tungsten chain cluster, Na-2[W3InO4(O2CEt)(8)](2)
, has been prepared from the self-assembly reaction of W(CO)(6), Na2WO
4 . 2H(2)O and InCl3 in propionic anhydride at 120 degrees C. The octa
metallic dianion, [W3InO4(O2CEt)(8)](2)(2-), consists of the two incom
plete cuboidal Units [W3O4(O2CEt)(8)](4-) which are centro-symmetrical
ly bridged by two In3+. The In3+ ions dissociate from the trinuclear u
nits in aqueous acidic solution.
