Synthesis and crystal structure of [K(C12H24O6)][U(η-C7H7)2], the first cycloheptatrienyl sandwich compound
Abstract
The title compound was prepared by treating a mixture of UCI4 and K with C7H8 or by reacting UCl4 with KC7H9; the crystal structure shows that the two C7H7 ligands are planar, parallel and perpendicular to the linear axis defined by the uranium atom and the ring centroids.
