In the solid state and also in solution CpM-L-E-Ph compounds adopt preferential conformations, in which C-H bonds of the Cp ligand bind to the pi system of the phenyl substituent. This holds for CpMo(CO)(2)-amidinato and -thioamidato as well as for CpM-P(OPh)(3) complexes. In the solid state this is demonstrated by short contacts CHCsp(2), retrieved in a CSD search, comparable to those in the archetypal T-shaped benzene dimer. In solution the CH/pi stabilization shows up in a typical high-field shift of the CpH signal, due to the anisotropy beam of the phenyl substituent, and in the thermodynamic stability of major and minor diastereomers in diastereomer equilibria. A special motif is the unsymmetrical bonding of two CpH bonds to the phenyl substituent, reminiscent of the new tilted T-shaped benzene dimer.
