COMPLEXES OF BINUCLEATING LIGANDS. VII. SOME COPPER(II) COMPLEXES OF TWO SULPHUR-CONTAINING LIGANDS

Abstract The following cupric complexes of the new binucleating ligand 2-hydroxy-5-methylisophthalaldehyde di-2′-methyl-mercaptoanil, (hereafter MeLH, the ligand strictly being the derived anion MeL−) and of the related trianionic ligand (hereafter L3-) formally derived from 2-hydroxy-5-methylisophthalaldehyde di-2′-mercaptoanil have been isolated and characterized:- Cu2(MeL)Cl3, Cu2(MeL)Br3, Cu3(MeL)Br5, Cu2(MeL)(OH)(ClO4)2, Cu2(L)Cl · DMSO, Cu2(L)(NCO), Cu2(L)(tz) (where tz is the anion of 1,2,4-triazole (tzH)). Magnetic properties are consistent with binuclear arrangements in all cases except Cu3(MeL)Br5.
