The preparation and characterization of Cu(II) complexes with N,N,N,N-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane and 2,6-diacetylpyridine bis(semi/thiosemicarbazones)
Two new Cu(II) mixed-ligand complexes with octadentate N,N,N,N-tetrakis(2-pyridylmethyl))-1,4,8,11-tetraazacyclotetradecane (tpmc) and potentially pentadentate ligands 2,6-diacetylpyridine bis(semicarbazone) (DAPsc2) or 2,6-diacetylpyridine bis(thiosemicarbazone) (DAPtsc2) were prepared.

| description | Two new Cu(II) mixed-ligand complexes with octadentate N,N,N,N-tetrakis(2-pyridylmethyl))-1,4,8,11-tetraazacyclotetradecane (tpmc) and potentially pentadentate ligands 2,6-diacetylpyridine bis(semicarbazone) (DAPsc2) or 2,6-diacetylpyridine bis(thiosemicarbazone) (DAPtsc2) were prepared. The general formulas: [Cu4 DAPsc2(tpmc)2]ClO4)8·5CH3COCH3·H2O and [Cu2 DAPtsc2(tpmc)](ClO4)4·7C2H5OH were proposed on the basis of elemental analyses and conductometric measurements. The complexes were characterized by magnetic measurement, electronic absorption and IR spectroscopy. For the dinuclear complex, an exo coordination of Cu(II) with four nitrogens from tpmc and m-bonded DAPtsc2 through sulfurs and possibly terminal hydrazinic (azomethine) nitrogens is assumed. For the tetranuclear complex, it is supposed that one DAPsc2 bridges two [Cu2 tpmc]4+ units using oxygens and terminal hydrazinic nitrogens as ligators. Finally, some antibacterial activity of the complexes was found. |
