The relevance of organometallic complexes in the chemistry of the interstellar medium(ISM) was first suggested in the early 90s. This initial proposal has recently beenre-considered in the light of new astronomical data, benefiting from pioneeringexperimental techniques and theoretical methods. In this article, a review of recenttheoretical and experimental results obtained for PAHs coordinated to Fe atoms ispresented, focusing on: -(i)- the IR spectra of [FePAH]+ and[Fe(PAH)2]+ complexes, found to be in line with the AIBs, withadditional specific features in the far-IR range and -(ii)- the photo-evaporation of[FexPAHy]+ clustersas possible candidates for very small grains releasing PAHs in photodissociation regions.These results call for new astronomical data at high spatial resolution. Studies on largerclusters will require further experimental and theoretical developments.
