The study focuses on replacing 2-methylimidazole with 1,2,3-triazole in zeolitic imidazolate frameworks, specifically ZIF-8 and ZIF-67.
This replacement leads to a complete transformation of the original framework's structure.
The resulting topological change shifts the framework from a sodalite (SOD) network to a diamond (DIA) network.

Bridging ligand replacement in zeolitic imidazolate frameworks, ZIF-8 and ZIF-67, by 1,2,3-triazole was investigated. A complete substitution of 2-methylimidazole by 1,2,3-triazole resulted in a topological transformation of the parent framework from a sodalite (SOD) network to a diamond (DIA) network.
