An Organometallic Erbium Bismuth Cluster Complex Comprising a Bi<sub>6</sub><sup>6–</sup> Zintl Ion
An organometallic erbium bismuth cluster complex, [K(THF)<sub>4</sub>]<sub>2</sub>[Cp*<sub>2</sub>Er<sub>2</sub>Bi<sub>6</sub>] (<b>1</b>), featuring a heterometallocubane core was isolated. The cube emerges from the rare Bi<sub>6</sub><sup>6-</sup> Zintl ion, bridging two erbium centers for the first time. SQUID magnetometry and <i>ab initio</i> calculations uncovered dominant antiferromagnetic coupling enabled through the chair-like hexabismuth anion. The gained insight will promote the design of future polynuclear magnetic molecules comprising prolate lanthanide ions.
