[Pb9CdCdPb9]6-: a Zintl cluster anion with an unsupported cadmium-cadmium bond.
Reaction of an ethylenediamine solution of the intermetallic Zintl phase K4Pb9 with dimesitylcadmium yielded the dimeric Zintl ion [Pb9Cd-CdPb9]6- in low crystalline yield. The cluster anion exhibits a Cd-Cd bond and was structurally characterised by single crystal X-ray diffraction in [K(2,2,2-crypt)]6[Cd2Pb18].2en (1). DFT was also used to explore the bonding in the hexa-anionic cluster.
