Imine-donor complexes with group 6 and group 11 transition metals : coordination and dynamics

[摘要] In this study the coordination of ligands with several coordination sites, 2-aminoazoles (2-amino-4-methylthiazole), 2-aminobenzothiazole, 2-aminobenzoimidazole and 2-aminothiazoline and a biguanidine (N-(2-methylphenyl)imidodicarbonimidic diamide) tosoft metal centres [gold(I) (group 11), chromium(0) (group 6) and tungsten (0) (group 6)]was investigated. The aminoazoles have three coordination sites, an exocyclic aminenitrogen, an endocyclic imine nitrogen and an endocyclic thioether sulphur. Thebiguanidine ligand has three sites for deprotonation, one central amine and two iminenitrogens, and at least five sites available for nitrogen coordination.
