摘要

Iron phthalocyanines with axial asymmetry are of considerable interest in catalysis and molecular electronics. The first iron phthalocyanine bearing water and cyano group as axial ligands is reported. The crystallization process from aprotic polar solvents is multistep, producing initially metastable structures with further transformations to stable 2:1 solvate crystals, which are determined by hydrogen bonding of solvate molecules with coordinated water and the interaction of cyano groups with the hydrogen atoms of the neighbouring phthalocyanine fragments. The influence of the solvents on the self-association of the phthalocyanine complexes is analysed, as well as their optical properties.
