Dichromate capture : A 3D cationic metal–organic framework consisting of distorted octahedral and tetrahedral cages was constructed by using Ag I and 4,4′‐bis(1,2,4‐triazole). The complex exhibits fast exchange, high trapping capacity, and good selectivity for Cr 2 O 7 2− through single‐crystal to single‐crystal transformation. The complex also features a bluish violet luminescence that is distinctly quenched after Cr 2 O 7 2− exchange.
