Cover Picture: Lindqvist-Type (Aryldiazenido)polyoxomolybdates − Synthesis, and Structural and Spectroscopic Characterization of Compounds of the Type (nBu4N)3[Mo6O18(N2Ar)] (Eur. J. Inorg. Chem. 15/2003)

Abstract The cover picture shows a hexamolybdate anion bearing a diazenido ligand. This is a member of a promising family of functionalized polyoxomolybdates [Mo 6 O 18 (N 2 Ar)] 3− with a variety of substituents on the aryl ring. The influence of these substituents on the properties of the molybdate framework is exemplified by their different 95 Mo NMR spectra, where a special attention should be drawn to the signal of the Mo II center at very high frequencies. Details on the preparation and characterization of these and related compounds can be found in the article by P. Gouzerh et al. on p. 2757 ff.
