  Synthesis, Characterization and Thermal Studies of Bipyridine Metal Complexes Containing Different Substituted Dithiocarbamates

  摘要：

  Complexes of the type [Mpy(2)(dedtc)(2)], and [Mpy(2)(dpdtc)(2)], where M = Mn(II), Fe(II), Co(II), Ni( II), Cu(II), Zn(II), py = pyridine, dedtc = diethyldithiocarbamate and dpdtc = diphenyl-dithiocarbamate, have been synthesized and characterized by elemental analyses, magnetic susceptibility, TGA/DSC and IR in the solid-state, and electronic spectroscopy and conductivity measurement studies in solution. The dithiocarbamato moiety has been found to be symmetrically bonded to the metal. The complexes are proposed to have a distorted-octahedral structure. The ligand field parameters 10 Dq, B and beta have also been evaluated. The value of b indicates a considerable orbital overlap in the complexes. A two-stage decomposition pattern leading to the formation of respective metal sulfide as the end-product has been observed in all the complexes. Their molar conductance indicated them to be non-electrolyte in nitrobenzene.

  Transition metal complexes (Mn --> Zn) of the dipyrromethane ligand, 1,9-dimesityl-5,5-dimethyldipyrromethane (dpm), have been prepared. Arylation of the dpm ligand alpha to the pyrrolic nitrogen donors limits the accessibility of the pyrrole pi-electrons for transition metal coordination, instead forcing eta(1),eta(1) coordination to the divalent metal series as revealed by X-ray diffraction studies.

• Zinc azaphthalocyanines with pyridin-3-yloxy peripheral substituents

  Phthalocyanines (Pc), which are peripherally substituted with pyridin-3-yloxy groups, have shown promise as sensitizers for photodynamic cancer therapy (PDT). Some aza-analogues (AzaPc) are reported here. Four monomers were synthesized, i.e. 5.6-di(pyridin-3-yloxy)pyrazine-2,3-dicarbonitrile, and three pyrazine-2,3-dicarbonitriles, substituted with pyridin-3-yloxy- in combination with H, Me and Ph groups. Cyclotetramerizations of these monomers with the reagent Zn(quinoline)(2)Cl(2) yielded the targeted ZnAzaPcs in 20-40% yields.The cyclotetramerizations were accompanied, and apparently initiated, by complexation between zinc(II) and the pyridin-3-yloxy groups attached to the pyrazine-dicarbonitriles. Two such zinc(II) complexes were isolated and characterized. Identifications of all new substances were primarily based on NMR spectra, where the pulse techniques COSY, NOESY, HSQC and HMBC were applied. Molecular ions of the ZnAzaPcs were determined by mass spectrometry (MALDI-TOF). The UV-Vis spectra of these macrocycles were as expected, with Q-band absorptions at 630-650 nm and molar extinction coefficients, epsilon, 70 000-100 000. Eight peripheral pyridin-3-yloxy groups induced a small blue shift of the Q-band, from 636 nm for unsubstituted ZnAzaPc, to 630 mn, whereas a red shifted Q-band at 650 nm resulted from the combination of phenyl and pyridin-3-yloxy substituents. Improved solubilities were observed for the unsymmetrical ZnAzaPcs compared to octa(pyridin-3-yloxy)ZnAzaPc. (C) 2009 Elsevier Ltd. All rights reserved.
