We report a simple and general method for the direct functionalization of the hexamolybdate cluster, [Mo[sub 6]O[sub 19]][sup 2[minus]], through which peripheral oxo ligands can be systematically replaced by a variety of organoimido groups. In the case of the 2,6-(diisopropylphenyl)imido ligand (hereafter referred to as NAr), we have discovered that multiple functionalization is readily achieved. The availability of these homologous oxo/(NAr) hexamolybdate derivatives provides an opportunity to examine how the electrochemical properties of the clusters respond to varying degrees of substitution. Cyclic voltametry studies in acetonitrile were conducted on the hexamolybdate and its mono-, bis-, and tetrakis(NAr) derivatives. Given the ready availability of various organic isocyanates, the present work suggests that it will be possible to logically design and rationally synthesize a broad range of hexamolybdate derivatives of potential utility. 11 refs., 3 figs.
