The structure of the title compound, [RhI(2)(C(3)F(7))(C(27)H(26)P(2))]·CH(2)Cl(2), at 110 (2) K is an unusual example of a structurally characterized square-based pyramidal alkyl complex of rhodium(III). The Rh-C bond is relatively short at 1.996 (6) Å. This short metal-carbon bond length is typical of perfluoro complexes of transition metals and illustrates the enhanced bond strength in these...
