Abstract
Method for making a Zn MOF of formula Zn2Ht2CL, where Ht is 1,2,4-triazolate or a combination of 1,2,4-triazolate and one or more other cycloazocarbyl compound, and CL is oxalate or a combination of oxalate and one or more chelating ligand other than oxalate. More specifically, the Zn MOF is Zn2Tz2Ox, where Tz is 1,2,4-triazolate and Ox is oxalate. The method includes reacting 2 molar equivalents of 1,2,4-triazole or the combination with cycloazocarbyl compound with 1 molar equivalent of oxalate or the combination with other chelating ligand and adding 2 molar equivalents of Zn2+ to form the Zn MOF. The solvent used can be a lower alcohol or a miscible mixture of water and a lower alcohol. One or both reaction steps are conducted at a temperature less than or equal to 120° C. and can be conducted at room temperature and ambient pressure.
