✦ Synopsis

Refluxing the tetraenic ether 1. with diironnonacarbonyl in benzene solution for 24 hr in a nitrogen atmosphere afforded five organometallic derivatives.1 The nmr spectrum of one of these, m.p. 200-204°C, suggested that this was a symmetrical bis-irontricarbonyl derivative of 1, of structure 1 or 2. An X-ray analysis has been carried out proving that the compound, m-p. 200-204° is 2.
