Molecular Structure of an Unusual Organoactinide Hydride Complex Determined Solely by Neutron Diffraction

Abstract
The structure of an unusual organometallic complex, {Th[(CH3)5C5]2 H(µ-H)}2 · C6H5CH3, has been determined from neutron diffraction data, using only the direct-methods program MULTAN. Besides providing accurate metrical information on the first organometallic actinide hydride complex, these results have general and far-reaching implications concerning the complexity and size of crystal structures that can be elucidated solely on the basis of neutron diffraction data.
