Résumé :

1,4,5,8-Tetraazaphenanthrenemetal tetracarbonyl complexes (metal = Cr, Mo, W) have been synthesized. The CO force constants show that there is more backbonding in these complexes than in the analogous 1,10-phenanthroline complexes, because of the two additional electron-withdrawing nitrogen atoms. The M→ L CT transitions show a strong bathochromic shift relative to the corresponding o-phenanthroline complexes. © 1979.
