An assignment of the IR bands for a free substituted phthalocyanine H 2[Pc (OC 8H 17 ) 8] , its sandwich type neodymium(Ⅲ) double and triple decker complex, Nd[Pc(OC 8H 17 ) 8] 2 and (Pc)Nd[Pc(OC 8H 17 ) 8]Nd[Pc(OC 8H 17 ) 8] has been done. It is found that in H 2[Pc(OC 8H 17 ) 8] and (Pc)Nd[Pc(OC 8H 17 ) 8]Nd[Pc(OC 8H 17 ) 8] the characteristic IR peaks appeared at 1330 cm -1 (w), 1380 cm -1 (s) and 1070~1080 cm -1 (rs) for bivalent phthalocynine anions: Pc 2- or Pc(OC 8H 17 ) 2- 8, and in Nd[Pc(OC 8H 17 ) 8] 2 the characteristic peaks appeared at 1315 cm -1 (rs) and 1380 cm -1 (s) were assigned for single phthalocyanine anion free radical.
