Figure . The crystal structure of the highly-substituted Pd2 diporphyrin (CCDC:VASKUY). Kobayashi and coworkers have investigated several aspects of nonplanar phthalocyanines. The series (ChPh A triply-fused diporphyrin (available as triply-fused-diporphyrin) from Osuka's group was characterized as the Cu and Zn chelates -both approximately planar. We can see the expansion of the core in the Zn example; in both, a tilda ("~", B3g) and double-twist (B2g) motifs are present, resembling the Lissajous curves (a=1, b=3, f = 0 and π/2).
