A cis configurated butadiene ligand which bridges two lanthanum nuclei, but forms a σ bond with one metal center and a π bond with the other, features in the title complex 1. Compound 1 can be prepared from “butadiene magnesium” as diene source (Equation (a)) and is isolated from pentane in the form of bright red, extremely air‐sensitive crystals.
