As a result of their different symmetry , the four structural isomers of the title compound (the C 4 h isomer 1 is depicted on the right) could be characterized by 1 H NMR spectroscopy. With these complexes the complete chromatographic separation of the four structural isomers of tetrasubstituted metal phthalocyanines was achieved for the first time. R 2‐EtC 6 H 12 O.
