Abstract:From the reaction mixtures containing Cu(ClO 4) 2 , bidentate ligands L (L = 1,10-phenanthroline, phen, or 2,2'-bipyridine, bpy) and KC(CN) 3 , pairs of [Cu(phen)(C(CN) 3) 2 ] n (1 and 2) and [Cu(bpy)(C(CN) 3) 2 ] n (3 and 4) complexes have been isolated. The composition of 1 and 2 on the one hand as well as 3 and 4 on the other hand is the same, nevertheless the IR spectra in the ν(C≡N) region of individual pairs of complexes were different and thus indicated different bonding modes of C(CN) 3 anions in indiv… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
