The reaction of the alkoxysilylcarbonylferrate [Fe(CO)3(η1-dppm){Si(OMe)3}]–1 (dppm = Ph2PCH2PPh2) with [SnCl2Ph2] affords a Fe2Si2Sn chain complex 2 and a FeSn2 complex 3 depending on the reaction conditions. Photochemical activation was found to trigger their transformation to another complex that has now been fully characterized by X-ray diffraction as trans, cis, cis-[Fe(CO)2(dppm-P,P)(SnClPh2)2] 6, which results from CO elimination and chelation of the dppm ligand.

RésuméLa réaction de l'alcoxysilylcarbonylferrate [Fe(CO)3(η1-dppm){Si(OMe)3}]–1 (dppm = Ph2PCH2PPh2) avec [SnCl2Ph2] conduit à un complexe en chaîne de cœur Fe2Si2Sn 2 et à un complexe FeSn23, en fonction des conditions de réaction. Une activation photochimique favorise leur transformation en un nouveau complexe, qui a pu maintenant être complètement caractérisé par diffraction des rayons X comme étant le trans, cis, cis-[Fe(CO)2(dppm-P,P)(SnClPh2)2] 6, qui résulte de l'élimination de CO et de la chélation du ligand dppm.
