Diagram illustrating the approach of methyl group hydrogens from the two distinct ligand orientations to the C–O of an adjacent molecule in [Fe(TPP)(CO)(1,2-Me2Im)]·C7H8. The major 1,2-dimethylimidazole orientation has H⋯OC distances of 2.50 Å and 2.69 Å, and the C⋯OC distance is 2.96 Å. In the minor orientation, the C⋯OC distance has increased to 3.68Å.
