The (dopf)Cu+ complex fragments (dopf = 1,1'-bis(diorganylphosphino)ferrocenes) can bind to the bidentate O:C-C-N function provided by isocaffeine (1,3,9-trimethylxanthine) and guanine heterocyclic systems in a variable semi-chelate coordination arrangement. Crystal structures reveal that the strong bond between Cu and N is complemented by a weak interaction between the O atom and Cu(I). While the ferrocene oxidn. behavior is conventional and not much different from that of related complexes of (dopf)Cu+ with lumazines, the structural variability of purine ligand coordination is unique and its implications are discussed. on SciFinder(R)
