โœฆ Synopsis

Natural abundance "N CP-MAS NMR spectra of copper(1) complexes and their ligands, [Cu(biL),]PF, [ biL = l,l&pbenanthroline (phen) and 2,~imethyl-l,l&phenanthroliae (Z,PMe,phen)l, were measured. Coordination shifts of -45 and -44 (average) ppm were obtained for phen and Z,PMe,phen, respectively, which are attributed to the stabilization of the nitrogen lone-pair orbital and the involvement of the metal d-orbital via n-back-bonding. KEY WORDS Natural abundance "N CP-MAS NMR Copper(1) complexes

Binuclear lanthanide(III)-silver(I) f3-diketonate chelates are effective N M R shift and relaxation reagents for substrates containing one or two multiply bonded nitrogen atoms, despite the fact that some of the substrates are able to react with lanthanide chelates alone. The silver cation is bonded
