Álvarez González, Celedonio Manuel García Rodríguez, Raúl Miguel San José, Daniel 2018-03-19T12:23:42Z 2018-03-19T12:23:42Z 2016 Dalton Transactions 2016, 45 , pp. 963 – 972 1477-9226 http://uvadoc.uva.es/handle/10324/29152 10.1039/C5DT01256B Producción Científica Metallamacrocycles of 12, 16, and 22 members are obtained by deprotonation of the carboxylic group of the side chain of iminopyridine complexes derived from the amino acid β-alanine, and the peptides Gly–Gly and Gly–Gly–Gly. Instead of the expected intramolecular attack to give tridentate (N,N,O) ligands, the deprotonated carboxylate attacks in an inter-molecular manner to give dimers in which the ligand acts as a bridge bonded in a κ2(N,N′) chelating fashion to one metal and as κ(O) to the other metal. The formation of the dimers is supported by NMR spectroscopy, mass spectrometry and X-ray crystallography.
