Sheltering under the roof : A trisimidazolium cage is capped with a {Fe II (bpy) 3 } 2+ subunit to produce a receptor that can bind small anions (bpy=2,2′‐bipyridine). Rodlike “pseudohalide” (N 3 − , NCO − , and NCS − ) and spherical halide (Cl − , Br − , and I − ) anions accept hydrogen bonds from CH fragments in the receptor cavity. The N 3 − ion forms the most stable inclusion compound (see structure; Fe red, C light blue, H white, N dark blue).
