摘要：

[La(Pc)(2)]. CH2Cl2 is prepared by anodic oxidation of ((n)Bu(4)N)[La(Pc(2-))(2)] as slightly soluble black needles crystallizing in the orthorhombic space group Pnma with a = 28.365(5), b = 22.935(3), c = 8.026(3) Angstrom, Z = 4. The La atom is in the center of an antiprismatic coordination polyhedron formed by the eight isoindole N atoms of the two staggered Pc ligands. The mean value of the La-N-iso bond distance is 2.51 Angstrom. One Pc ligand is quasi planar, the other is convex. The electronic absorption spectra and IR and resonance Raman spectra of the partially oxidized La-III diphthalocyanine are reported and compared with those of the protonated complex H[La(Pc(2-))(2)].
