Redox chemistry of cerocene: the first heterobimetallic organolanthanide complex†
Abstract
The first heterobimetallic organolanthanide complex containing two different rare earth elements, [Yb(thf)6][Ce- (cot′′′)2]2 2 [cot′′′ = η8-1,3,6-(Me3Si)3C8H5], has been prepared by reacting neutral [Ce(cot′′′)2] with Yb metal in THF; the crystal structure of 2 consists of separated [Yb(thf)6]2+ and [Ce(cot′′′)2]– ions.
