Single‐crystal X‐ray structures of a) Sr²⁺⊂ZJU‐X100 and d) Cs⁺⊂ZJU‐X102. Encapsulation of b) Sr²⁺ within the cavity of 18‐crown‐6 group of ZJU‐X100 and e) Cs⁺ within the cavity of 24‐crown‐8 group of ZJU‐X102. c) Representation of the Sr²⁺ inclusion complex in Cs⁺⊂ZJU‐X100, showing the relative positions of Sr²⁺ and crown ether and coordinated water molecules. f) Conformation of dibenzo‐24‐crown‐8 in ZJU‐X102 before and after complexation with Cs⁺. Atom colors: Sr, green; Cs, sky blue; O, red; C, and light grey. Hydrogen atoms were omitted for clarity.
