COPPER (II) AND PALLADIUM (II) COMPLEXES WITH 1,3-BIS-[3-(5-AMINO-1,2,4-TRIAZOLYL]TRIAZENE AND HALOGENO (PSEUDOHALOGENO) LIGANDS - SYNTHESIS AND SPECTROSCOPIC CHARACTERIZATION

The title ligand (hereafter abbreviated as BATTH) is composed of a triazenic and two triazolic functional groups. The synthesis of metal complexes of general formula [M(BATT)X] (M=Cu(II), X=Cl, Br, I, SCN, CN; M=Pd(II), X=Cl, Br), and of the intermediate product [Cu(BATT)H2O]NO3 are reported. These complexes (including N-15 isotopes) are characterized by IR, micro-Raman, NMR (H-1, C-13) and UV-visible spectroscopies. From these results, it is proposed that BATT-adopts a terdentate-planar mode of coordination involving the two triazole cycles and the N2 atom of the triazenido group, which appears as a new type of coordination for this group.
