The title compound has been synthesized by reacting (AuCl)2(μ-dppfe) with LiCo3(CO)10 in THF at room temperature. The IR spectrum of this product in the ν(CO) region has shown that each of the three peaks observed for a solution sample splits into a doublet in the solid. Single crystal X-ray analysis has revealed that the P-Au-Co-CO(axial) skeleton makes a pair in a head-to-tail manner with neighboring molecules. The Au-Au separation in the pair is 5.6220(8) Å, which is far beyond the regime of the normal aurophilic interaction. By comparing the results with those of analogous Mn compound, that is, [AuMn(CO)5]2(μ-dppfe), it has been concluded that the pair formation between the neighboring molecules is responsible for ν(CO) splitting of [AuCo(CO)4]2(μ-dppfe).
