Ternary intermetalloid cluster : The first intermetalloid M/13/15 Zintl anion [(La@In 2 Bi 11 )(μ‐Bi) 2 (La@In 2 Bi 11 )] 6− was obtained upon reaction of [InBi 3 ] 2− with [La(C 5 Me 4 H) 3 ] in ethane‐1,2‐diamine (see scheme). DFT calculations served to analyze and explain the Lewis acid/base interaction upon assignment of formal charges as “Bi + ←In 2− ”, which discriminates the anion from an isoelectronic La/Sn/Bi analogue that does not require bridging.
