Abstract

Thermal reaction of the ethynediyl complex [{Ru(CO)₂(μ-C₅H₅)}₂(μ-C≡C)] (1) with diiron nonacarbonyl occurs with formation of [Fe₂Ru₂(μ₄C≡C)(μ-CO)(CO)₈-(η-C₅H₅)₂] (2), a cluster containing a bicarbide ligand. A structural study has shown that one of the ruthenium atoms migrates from a position where it is σ-bonded to a single ethynediyl carbon to become μ²-bonded to the ethynediyl unit. Complex 2 crystallizes in the monoclinic space group P2₁/c with a = 9.579 (5) Å, b = 24.789 (4) Å, c = 10.621 (5) Å, β = 115.02°, Z = 4, V = 2285 (2) Å³, 2679 reflections with I ≥ 3σ(I), R = 0.049, R_w = 0.056.
