## Abstract The aromatic ^1^H‐ and ^13^C‐NMR. spectra of some metal complexes of o, o′‐dihydroxyazobenzenes are shown to be useful in distinguishing the two possible isomers (acolar and discolar) stemming from the non equivalence of the two ligating azo nitrogen atoms. The ortho aromatic carbon ato

Dilithium naphthalene (2) and its TMEDA complex 3 have been prepared, and their 'Hand I3C-NMR spectra were analyzed in terms of chemical shifts and coupling constants. From its Q value, 2 is characterized as delocalized [4n] B system and the 'H-as well as the 6Li-NMR shifts classify the ion as stron
