The first structurally characterized homoleptic metal-alkyne cluster 3 is formed from bis(trimethylsilyl)ethyne and the complexes 1 and 2, which are obtainable by cocondensation. The yield of 3 with respect to vaporized iron is 30–50%. 3 is diamagnetic, so that in spite of the relatively large iron-iron distance (2.465 Å) the presence of an iron-iron double bond must be assumed.
