The back cover picture shows the molecular structure of the niobium ureate complex derived from N 2 and CO 2 . The niobium nitride prepared from N 2 activation by niobium hydride was alkylated with methyl iodide to afford the imide complex, which was converted to the ureate complex upon exposure to CO 2 in the presence of pyridine. Protonation of the nitride complex yielded ammonia along with niobium chloride, which could be recycled back to the niobium hydride. Details are discussed in the article by H. Kawaguchi et al. on p. 3930 ff .
