CATENATED NITROGEN LIGANDS PART 1. TRANSITION METAL DERIVATIVES OF TRIAZENES, TETRAZENES, TETRAZADIENES, AND PENTAZADIENES... 

This review, which complements an earlier one (Part I) dealing with transition metal complexes of triazenes, tetrazenes, tetraazadienes, and pentaazadienes, examines the coordination chemistry of related cyclic catenated nitrogen ligands. Six-membered rings containing three, four, or five adjacent nitrogen atoms — 1,2,3-triazines, 1,2,3,4-tetrazines, and pentazines, respectively — are either unknown or are relatively unstable species whose coordination chemistry has yet to be explored.
