Figure 2
Diagram of the porphyrinato core of the title compound. Mean values of the chemically unique bond lengths (in Å) and angles (in °) are shown. The numbers in parentheses are the s.u. calculated on the assumption that the averaged values are all drawn from the same population. The perpendicular displacements (in units of 0.01 Å) of the porphyrin core atoms from the 24-atom mean plane are also displayed. Positive values indicate a displacement toward the N7 2-methylimidazole nitrogen atom. The solid line in this perspective indicates the 2-methylimidazole ligand containing atom N7, and the dashed line indicates the 2-methylimidazole ligand containing atom N5. The small circle represents the position of the methyl group on the axial ligand. |
