title: Self-coupling of a 4-H-butatrienylidene tungsten complex.
abstract: Tungsten tryst: A 4-H-butatrienylidene complex of tungsten was successfully isolated and structurally characterized. It undergoes a unique self-coupling, which leads to a dimer (see picture; P pink, O red) with a cross-conjugated pi system and with electrochemically and magnetically active metal centers.
