The structure of Di-mu-chloro-bis(trichlorobis(tetrahydrofuran)uranium(IV)) is analysed, using 1287 observed unique reflections. The dimeric complex, in which two UCl(4)(THF)(2) moieties are bridged by two Cl atoms, lies on a centre of symmetry. Each U atom of the dimer is seven-coordinated in a pentagonal-bipyramidal geometry. The maximum deviation from the best plane through the U atom and its five equatorial ligand atoms (Cl(1), Cl(1)(i), Cl(4) and the O atoms of the two THF) is 0.05(1) Angstroms. Cl(2)-U-Cl(3) is almost linear and perpendicular to this plane.
