Figure 2
A formal diagram of the porphinato core of the title compound. Averaged values of the chemically unique bond length (Å) and angles (°) are shown. The numbers in parentheses are the standard uncertainties calculated on the assumption that the averaged values were 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. Negative values indicate a displacement toward the N7 1-ethylimidazole nitrogen atom. The solid line in this perspective indicates the 1-ethylimidazole ligand containing atom N7, and the dashed line indicates the 1-ethylimidazole ligand containing atom N5. The circle represents the position of the ethyl group on the axial ligand. |
