Self-Assembly of Trigonal-Prismatic Metallocages Encapsulating BF4− or CuI32− as Anionic Guests: Structures and Mechanism of Formation

Thermodynamically stable, but kinetically labile: Trigonal‐prismatic M3L2 metallocages occur in [BF4⊂{Ag3(MsTBim)2}](BF4)2 (1) and [{CuI3⊂[Cu3(MsTBim)2]}2](Cu2I4) (2), the latter with an unprecedented metal‐complex‐host/metal‐complex‐guest arrangement. Large anions such as CF3SO3− or BPh4− have to r...

Description
Summary:Thermodynamically stable, but kinetically labile: Trigonal‐prismatic M3L2 metallocages occur in [BF4⊂{Ag3(MsTBim)2}](BF4)2 (1) and [{CuI3⊂[Cu3(MsTBim)2]}2](Cu2I4) (2), the latter with an unprecedented metal‐complex‐host/metal‐complex‐guest arrangement. Large anions such as CF3SO3− or BPh4− have to reside outside the cage facing its “windows”. MsTBim=1,3,5‐tris(benzimidazol‐1‐ylmethyl)‐2,4,6‐trimethylbenzene.
