Formally only 12 valence electrons are assigned to the Rh I atom in the cyclo ‐M 3 clusters in the title. This electron deficiency is compensated by π‐electron delocalization in the M 1 ‐Rh‐M 2 three‐membered ring, and the unusual threefold coordination of the d 8 ‐Rh I atom (see picture on the right) is thus stabilized. The cluster can be synthesized in good yields from [Rh(CO)(PPh 3 )]Cl and PPh 4 [M 1 M 2 {μ‐P(C 6 H 11 ) 2 } CO 8 ].
