Heteroleptic protonated bis(phthalocyaninato) rare earth compounds containing 1,4,8,11,15,18,22,25-octa(butyloxy)-phthalocyanine ligand

Abstract Condensation between M(Pc)(acac) (M = Sm, Eu, Gd; Pc = phthalocyaninate; acac = acetylacetonate) and metal-free 1,4,8,11,15,18,22,25-octa(butyloxy)phthalocyanine in n -octanol afforded heteroleptic double-deckers H{M(Pc)[Pc(α-OC 4 H 9 ) 8 ]} [Pc(α-OC 4 H 9 ) 8  = 1,4,8,11,15,18,22,25-octa(butyloxy)phthalocyaninate]. The series of double-decker complexes were characterized by elemental analysis, mass spectra, electronic absorption spectra, and IR spectra. The molecular structure of the compound of Gd was determined by single-crystal X-ray diffraction analysis. It was found that it exists as a pair of enantiomers in the unit cell of the crystals. Furthermore, the complex of Sm reacted with NaOH producing a supramolecule in which two Na + ions connect two double-deckers together.
