Figure 5. Structure of iron(phthalocyanine) within the faujasite cavity as calculated via molecular mechanics. Carbon and hydrogen atoms of the metal complex are shown as unshaded dark and open circles respectively. Silicon and oxygen atoms of the zeolite are shown as shaded circles. Two views are given, (a) Along the S4 direction in the cavity with two phenyl rings of the metal complex emerging from the tetrahedral holes in the direction of the viewer and the other two rings in the tetrahedral holes away from the viewer, (b) Perpendicular to the S4 axis showing phenyl rings in their tetrahedral holes. The backbone of the metal complex and faujasite cavity are shown.

In the past 15 years, a number of reviews have appeared. Two general reviews appeared in the mid 70s Both of these reviews attempted to comprehensively survey the topic of porphyrin stereochemistry up to the time of publication. These two reviews are appropriately consulted for complete information of all work completed to that time. In addition, there have been a number of more specialized reviews pertaining to tetrapyrrole macrocyclic structure. An excellent article by Glusker has detailed the structural work on vitamin B12 derivatives. An early classic review examined the stereochemistry of hemes (iron porphyrinates) and their relationship to the function of the hemoproteins A review of trends in metalloporphyrin stereochemistry as a function of electronic state and position in the periodic table was written by the author in 1977 There are also two subsequent reviews in which the senior author has participated a 1983 article (with Martin Gouterman) that attempted to reach an understanding of control of spin state in metalloporphyrins and a 1981 article (with Christopher A. Reed) that catalogues spin-state/stereochemical relationships of the iron porphyrinates and the implications of these structures for the hemoproteins. Articles by Hoffinan and Ibers have discussed the use of oxidized porphyrins and phthalocyanine derivatives as molecular metals. It is not the intention of the present review to attempt to supplant any of these earlier reviews but rather to extend them when appropriate, new information is available. Further, we will review some additional topics that have not been considered previously.
