Complexes of zinc phthalocyanine with monoaxially coordinated irnidazole-derivative ligands
Three complexes of zinc phthalocyanine (ZnPc) monoaxially ligated by imidazole, N-methylimidazole and N-(2-pyrimidinyl)imidazole were obtained in crystalline forms. Complexes containing imidazole and N-methylimidazole crystallise in the centrosymmetric space group of the triclinic system, while with the N-(2-pyrimidinyl)-imidazole complex crystallises in P2(1)/n space group of monoclinic system. Interaction of the electropositive polarised Zn centre of a planar ZnPc with nucleophilic ring nitrogen atom of imidazole derivatives leads to deviation of Zn form the N-4-plane of phthalocyaninato(2-) macrocycle by similar to 0.45 angstrom. Steric hindrance of the axial ligands of ZnPc-L complexes modify the pi center dot center dot center dot pi interactions between the Pc(2-) macrocycles when compared to that of the parent ZnPc pigment. The calculated threedimensional MESP maps are helpful for understanding of the interaction between the ZnPc and imidazole derivatives forming the monoaxially ligated complexes. Theoretical calculations of axial bonds energies and UV-Vis spectroscopic measurements in solutions also were performed. (C) 2016 Elsevier Ltd. All rights reserved.
