| Abstract: | Paramagnetic complexes CuL1SO4·0.5H2O, CuL2SO4·2H2O and diamagnetic Pd(HL2)Cl3 (L1 = 2-methyl-1,3,11,11c-tetraazacyclopentac]phenanthrene complex (L2 = 2-phenyl-1,3,11,11c-tetraazacyclopenta-c]phenanthrene) were synthesized. The most probable structure of the complexes was suggested on the basis of the IR and ESR
spectra. Coordination units of paramagnetic complexes contain N atoms of the bidentate cycle-forming ligands, L1 and L2 molecules. The square PdCl3N unit of the diamagnetic complex includes the N atom of the triazole fragment of the monodentate ligand, (HL2)+ cation. |
