The infra-red spectroscopic data for a series of 88 sandwich-type (na)phthalocyaninato and porphyrinato rare earth complexes, including heteroleptic double- and triple-deckers, have been collected and systematically studied. The IR characteristics for unsubstituted and substituted (na)phthalocyaninato monoradical anion Pc' - (Pc'=Pc, Pc*), Nc' - (Nc'=Nc, Nc*), and dianion Pc' 2 - (Pc'=Pc, Pc*) are thus comparatively described.
