Abstract
An organometallic erbium bismuth cluster complex,[K(THF)4]2[Cp*2Er2Bi6] (1), featuring a heterometallocubanecore was isolated. The cube emerges from the rare Bi66− Zintl ion,bridging two erbium centers for the first time. SQUID magneto-metry and ab initio calculations uncovered dominant antiferro-magnetic coupling enabled through the chair-like hexabismuthanion. The gained insight will promote the design of futurepolynuclear magnetic molecules comprising prolate lanthanideions
