Abstract
Superbulky sandwich complexes with the cyclopentadienyl ligand (4-nBu-CH)Cp (abbreviated here as Cp ) have been prepared by reaction of CpH with benzylic strontium or barium reagents. Both metallocenes have been structurally characterized by single crystal X-ray diffraction. Even for the larger metallocene (Cp)Ba a highly symmetric sandwich complex with parallel Cp rings was isolated (Cp-Ba = 2.667(1) Å). Both structures show evidence for a C-H...C(π) network between the Cp ligands. These attractive forces induce an inward out-of-plane bending of the aryl substituents (Sr 3.4(2)°; Ba 5.3(2)°). A linear correlation between this bending angle and metal size has been found. © 2008 The Royal Society of Chemistry.
