✦ Synopsis
Abstract
The dipyrroloimidazolyl ligand is found to bind the pentacarbonylmanganese group to its central ring via a carbon‐metal σ‐bond. This bonding mode differs greatly from that of known imidazole complexes and from the pentahapto mode encountered with the isoelectronic fluorenyl ligand. The X‐ray structure of the title compound is reported.
