4 Reactions With Nine-Atom Deltahedral Zintl Anions of Tin 

It was shown later that similar reactions can be carried out with the heavier congeners in the Cr group. 

Mo and W. It is now known that both Sn and Pbg can be derivatized with M(CO)3 where M = Cr, Mo, or W to form bicapped square antiprisms where the transition metal caps one of the squares. (It is somewhat surprising that no analogous [Ge9M(CO)3] clusters have been characterized to date.
