From 2-methylimidazole to 1,2,3-triazole: a topological transformation of ZIF-8 and ZIF-67 by post-synthetic modificationElectronic supplementary information (ESI) available. See DOI: 10.1039/c6cc08746a

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. We report the first examples of the simultaneous non-assisted replacement of ligands and the conversion of topology in MOFs by applying the PSM approach.
