The first experimental evidence is presented for planar–bent isomerism of complexes of the type [L 4 M 2 (μ‐X) 2 ]. Both the planar and bent forms have been detected for the same composition , [(Ph 3 P) 4 Rh 2 (μ‐F) 2 ], with full exclusion of any variation in such factors as the nature of the metal, ligand, counterion, and solvent of co‐crystallization. Computationalstudies point to weak C–H ··· F intramolecular bonding as an additional factor affecting the choice between the planar and bent geometries. (© Wiley‐VCH Verlag GmbH & Co.
