The structure of Tris (1-3-n-indenyl)-iodouranium is described. The title compound is not isostructural with its Cl and Br analogues although the geometry of the coordination polyhedron about the U is identical in the three derivatives. The U atom is surrounded by three indenyl rings and one iodide atom in an approximately tetrahedral configuration. As for U.[C(9)H(7)](3).Cl and U.[C(9)H(7)](3).Br, the orientation of the indenyl rings and the shorter bonds observed between the U atom and the three non-bridging C atoms from the five-membered ring of each indenyl moiety suggest a trihapto character of the metal-carbon bonding.
