The crystal structures of two monopentamethylcyclopentadienylhafnium(IV) derivatives have been determined by X-ray diffraction analysis. The [Hf(η5-C5Me5)Cl3] complex (I) crystallizes as a dimer in the monoclinic space group C2/c with Z = 8. The structure of I is described as two {Hf(η5-C5Me5)Cl2} units linked by two bridging chloride ligands. The [{Hf(η5-C5Me5)Cl}3(μ-Cl)4(μ3-O)] complex (II) crystallizes in the monoclinic space group Cc with Z = 4. The structure of II is described as three {Hf(η5-C5Me5)Cl} moieties connected by one or two bridging μ-chloride ligands and an additional μ3-oxide group. The hitherto unknown compound II has also been characterized by spectroscopic and analytical methods. In the solid state, the molecules of both derivatives are linked by C–H⋅⋅⋅Cl hydrogen bonds and C–H⋅⋅⋅π interactions, providing an alternating layered pattern. [ABSTRACT FROM AUTHOR] |
