Imidazole-containing chelate ligands

Complexes of the stoichiometry [ML3] [C104]2 [L = thiabendazole (65)] contain the metal in an octahedral coordination with the chelating ligand coordinated via the nitrogens of the imidazole and thiazole rings.465... 

Hydrogenated products of the pyrazoles and the imidazoles, i.e. the pyrazolines and imidazolines, have some importance as ligands, but have seldom been reported. Only some chelate ligands containing imidazoline have been studied in some detail and will be discussed in Section 13.2.5.3. 

The structure of (9-methyladenine)ZnCl2 is polymeric each zinc ion is tetrahedrally co-ordinated to two chlorine atoms (Zn—Cl = 2.22 AX and to N(l) and N(7) of neighbouring adenine moieties (Zn—N = 2.05 A).Complexes of the stoicheiometry [ML3][C104]2[L = thiabendazole (1)] contain the metal in an octahedral co-ordination with the chelating ligand co-ordinated via the nitrogens of the imidazole and thiazole rings.
