Drastic structural changes in an anionic carbonylmetal cluster can be evoked by slight changes in the acid/base properties of the system. In the crystalline title compound (X‐ray structure analysis) edge‐bridging CO groups are present in the cluster units. In contrast, the IR spectrum recorded in ether indicates an equilibrium between (a few) clusters of this kind and (mainly) clusters having terminal CO groups.
