    • The four Zn atoms are coplanar and describe an approximate rhombus. Distances (Å): Zn1-Zn2 8.330(1), Zn1-Zn2* 8.558(1), Zn1-Zn1* 9.073(1). The mean planes of the two independent porphyrin macrocycles make angles of 65 and 85° to the rhombus plane, and the two central porphyrin rings (blue/green) are 8.77 Å apart.

    • Although coordination of the amine function to the metal is also conceivable, there is no evidence that this ever occurs in the case of 2-aminopyrimidine.

    • While the noncoordinating pyrimidinic nitrogens have negative partial charges (-0.17), ligation of a porphyrinic zinc atom leads to a partial positive charge (+0.11) which enhances the polarization of the neighbouring N-H bonds leading to tighter inter-tetrameric hydrogen bonding.

    • Six of the sites are only half occupied in the crystal, resulting in a molecular formula containing 23 cyclohexane molecules.
