An Organometallic Erbium Bismuth Cluster Complex Comprising a Bi₆^6- Zintl Ion.

ABSTRACT: An organometallic erbium bismuth cluster complex, [K(THF)₄]₂[Cp*₂Er₂Bi₆] (1), featuring a heterometallocubane core was isolated. The cube emerges from the rare Bi₆^6- Zintl ion, bridging two erbium centers for the first time. SQUID magnetometry and ab initio 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.
