trinuclear ion Mo3S4(H2O)9]4+ to give cuboidal complexes of the kind Mo3MS4, or related edge-linked species {Mo3MS4}2, or corner-shared Mo3S4MS4Mo3 double cubes, depending on the heteroatom used. All of the products formed can be obtained as aqua ions. With four recent additions there are now 15 different heterometal atoms participating in this chemistry from Cr in Group 6 to Bi in Group 15. Preparative procedures, X-ray crystal structures, and distinctive properties including UV-Vis spectra, elution characteristics using Dowexcation exchange chromatography, ICP metal analyses, and the stoichiometries of reactions in which the heterometallic product is oxidized back to Mo3S4(H2O)9]4+ (with release of the heterometal in an ionic form) are considered.Dedicated to Professor Jiaxi Lu on the occasion of his 80th birthday. |
