Synopsis
Complexes containing pyridine-2-carboxaldehyde (pyca) ligand acting as κ2-(N,O) are good precursors for iminopyridine complexes derived from amino esters and peptides. In solid phase the peptide chains assemble through H-bonds adopting different patterns which depend on the geometry of the metal−ligand fragments. DOSY experiments show the H-bonding interaction between the peptide and O═PBu3.

Synopsis

The existence of a strong hydrogen bond between two molecules of an (alkoxoimino)pyridinemanganese(I) complex induces their dimerization and the formation of a metallamacrocycle. The expected intramolecular attack of the alkoxo moiety is disfavored.
