The preparation of many complexes of bipyridyl-containing metals in low oxidation states have been achieved by Herzog and his co-workers (e.g., 367). These and other compounds of interest are cited in Table XVI together with magnetic moments measured at ambient temperature (the most widely determined property). Although most work has been carried out with bipyridyl, it is apparent that phenanthroline and terpyridyl will afford similar complexes. There is a general paucity of physical data for the compounds listed in Table XVI. The determination of magnetic susceptibilities as a function of temperature would be worthwhile in many cases and the two iron compounds are obvious candidates for a Mossbauer study. 

For example Cn(tmen)(acac)C104, where tmen = N,N,N ,N -tetramethylethylendi-amine and acac = acetylacetonate, has be snccessfully used as a Lewis-basicity indicator, and Fe(phen)2(CN)2, where phen = 1,10-phenanthroline, as a Lewis-acidity indicator. The physical origin of the imderlying color changes is sketched in the Figure 12.1.3, as modified from ref. These color indicators can be applied as a quick method for assessing the coordination properties of solvents, solvent mixtures, and solutes not yet measiued.
