Monomeric complexes MLnXm, where M = Co2+, Ni2+, Zn2+, Cd2+, Cu2+, Pd2+, Sn4+; L = 1-allenylimidazole, 1-allenyl-2-methylimidazole, 1-allenylbenzimidazole; n = 2, 4; m = 1, 2, 4; X = Cl, OCOCH3, was prepared for the first time, and their structure was studied by NMR and IR spectroscopy. In the complexes, 1-allenylimidazoles act as monodentate ligands, coordinating via the heteroring N-3 atom, and the CH2=C=CH group is stabilized by coordination of the azolyl ring with the metal, which hinders electron transfer from the heteroring to the allenyl fragment. The prospective use of the complexes of Zn(OCOCH3)(2) with 1-allenyl imidazole derivatives as antidotes and antihypoxants was demonstrated.
