    • The vinyl and methyl substitutents of the starting heme monomer were modified according to the different stereoisomers, and all hydrogen atoms were inserted into chemically and crystallography reasonable positions. The length of the double bond in the vinyl group was adjusted to the expected value of 1.35 Å, considerably longer than the reported length of 1.25 Å. The short length could be interpreted as arising from diastereoisomeric disorder of the vinyl and methyl groups of pyrrole rings B and C.

    • The average lateral shift between the two Fe(3+) ions in the isolated Fe-O dimer is 6.8 Å, and the perpendicular distance between the two porphyrin rings is 4.9 Å, as compared with 8.4 and 4.6 Å in the crystal. We note, however, that solvation may effect the structure of the dimers in solution.

    • It is possible also to form O-HO bonds between carboxylic acids by 2-fold screw symmetry, which has a very rare occurrence for molecular systems and would impose stringent constraints on the molecular packing.
