We report on the synthesis of two new Zn metal–organic frameworks with 1,3-tetrazolatephenyl-acetic and 1,4-tetrazolatephenyl-acetic spacers obtained in situ by hydrothermal routes. These three-dimensional structures exhibit intense blue-green long lifetime photoluminescence emission at room temperature in the solid state. To the best of our knowledge, this is the first time that coordination compounds have been synthesized with these ligands.
