Structure of zinc phthalocyanine by gas phase electron diffraction

Abstract

Gas phase electron diffraction data have been successfully recorded for zinc phthalocyanine. Molecular structure parameters have been determined by least square fitting a geometrically consistent model of C4v symmetry to the data. The results agree well with previous x-ray diffraction studies of crystals. However, the zinc atom was found to be slightly out the plane of the molecule in contrast with the x-ray results.
