✦ Synopsis

It is shown that it is possible to obtain structural information from small (`100 nm) phthalocyanine crystals by using crystallographic direct phasing methods applied to electron diffraction data. This technique is both quantitative and does not suffer from the difficulties associated with high-resolution electron microscopy. Structural information has been obtained from both tetra-and octa chloro-copper phthalocyanines, and the results compared with the hydrogenated and perchloro members of the series.
