The cluster [Rh11(CO)14(C7H7)3] (1) was obtained from the reaction of [Rh6(CO)16] and an excess of cycloheptatriene in refluxing toluene. Initially, the substituted cluster [Rh6(CO)13(C7H8)] (2) could be identified spectroscopically, which is transformed into 1 after prolonged refluxing. In the solid state, the eleven rhodium atoms define a trioctahedral metal cage, condensed through a common edge. The three planar, equivalent C7 rings sit on the top of triangular faces. The spectroscopic characterisation of the product is hampered by its low solubility. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
