Thermodynamically stable, but kinetically labile : Trigonal‐prismatic M 3 L 2 metallocages occur in [BF 4 ⊂{Ag 3 (MsTBim) 2 }](BF 4 ) 2 ( 1 ) and [{CuI 3 ⊂[Cu 3 (MsTBim) 2 ]} 2 ](Cu 2 I 4 ) ( 2 ), the latter with an unprecedented metal‐complex‐host/metal‐complex‐guest arrangement. Large anions such as CF 3 SO 3 − or BPh 4 − have to reside outside the cage facing its “windows”. MsTBim=1,3,5‐tris(benzimidazol‐1‐ylmethyl)‐2,4,6‐trimethylbenzene.
