Complexes of Cu(II) and Pd(II) with 2-R-1,3,11,11c-Tetraazacyclopenta[c]phenanthrenes

摘要

Paramagnetic complexes CuL ~1SO4·0.5H2O, CuL ~2SO4·2H2O and diamagnetic Pd(HL~2)Cl3 (L~1 = 2-methyl-1,3,11,11c-tetraazacyclopenta[c]phenanthrene complex (L~2 = 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, L~1 and L~2 molecules. The square PdCl3N unit of the diamagnetic complex includes the N atom of the triazole fragment of the monodentate ligand, (HL~2)~+ cation.
