  摘要：

  Interaction of CO with sublimed layers of iron(II) meso-mono-4-pyridyltriphenylporphyrinate (FeM4PyTPP) resulting in the formation of known mono- and dicarbonyl complexes was studied using IR spectroscopy. The frequency of the stretching vibration of the coordinated CO in the monocarbonyl complex was found to be similar to 20 cm(-1) higher than in the complex with iron meso-tetraphenylporphyrinate (FeTPP), with the former complex being significantly more stable than the latter. The differences observed in CO coordination by porphyrins with close structures are explained by the formation, in the FeM4PyTPP sublimed layers, of oligomeric structures where the pyridyl group of one molecule is coordinated by the metal ion of the neighboring molecule. This conclusion is confirmed by a comparative analysis of IR spectra of FeM4PyTPP and FeTPP in the regions of structurally sensitive vibrations.

  Low-temperature (T = 80 K) interaction of the sublimed layers of meso-mono-4-pyridyltriphenylporphyrinatoiron(II) (FeMPyTPP) with dioxygen was studied by IR and electronic absorption spectroscopies. Unlike the meso-tetraphenylporphyrinatoiron(II) (FeTPP) layers, coordination of O-2 with FeMPyTPP produces extra-complexes of two types: in the first complex one of the axial sites is free, while in the second complex an axial site is occupied by the pyridine group of the adjacent molecule. The results obtained indicate self-assembly of the FeMPyTPP molecules through coordination bonds between the iron atom and pyridine group of the adjacent molecule in the layer. The bonding of O-2 by the sublimed FeMPyTPP layers differs substantially from that by the FeTPP layers, which rapidly loose their ability of oxygen bonding at room temperature.
