Oxo-Bridged Bimetallic Organouranium Complexes: The Crystal Structure of m-Oxo-Bis[Tris(Cyclopentadienyl) Uranium (IV)]
Oxidation of (C(5)H(5))(3)U(III). THF with oxygen in tetrahydrofuran yields the linear bridged complex [(C(5)H(5))(3)U](2)[m-O]. Three cyclopentadienyl rings are eta(5) covalently bonded to each uranium atom to form a distorted tetrahedron with one bridging oxygen atom. The U-O-U angle is 180 with the oxygen atom on a centre of inversion. The U-O distance, 2.0881(4) angstroms, is among the shortest ever observed. The temperature-dependent paramagnetic susceptibility of the compound was measured in the temperature range between 4.2 and 300 K and is discussed in comparison with the magnetic susceptibilities of (C(5)H(5))(3)UOH, (C(5)H(5))(3)USH and [(C(5)H(5))(3)U](2)[m-S).
