Presented here is a water-stable zeolite-like metal–organic framework material AgIn(ina)4 (1; ina = isonicotinate) integrating two special tetrahedral building units ([AgN4]+ and [In(COO)4]−), which can rapidly adsorb methyl orange (MO) over methylene blue (MB) from water in 6 minutes and release MO in an easy way.
