A π(CC)‐δ(MM)‐π(CC) electron framework exists in the title compound 1 , the simplest complex of the type [M 2 (CCR) 4 (PMe 3 ) 4 ], and the first to be characterized by X‐ray crystallography. This dimetallapolyyne differs from the more highly substituted derivatives in its electronic properties; however, in several instances, the properties of 1 closely parallel its nearest organic analogue, the tetraethynylethene C 10 H 14 . L = PMe 3 .
