摘要：

A cis configurated butadiene ligand which bridges two lanthanum nuclei, but forms a sigma bond with one metal center and a pi 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.
