Abstract

An aliovalent mixed-metal framework DUT-174 [LiAl(2-methylimidazolate)₄]_n, isostructural to ZIF-8, was synthesized from lithium aluminum hydride (LiAlH₄) and 2-methylimidazole (2-mImH) through dehydrogenation. Lithium and aluminum cations acting as alternating framework nodes are coordinated tetrahedrally by (2-mIm)^-. DUT-174 has a high specific surface area of 1149 m² g⁻¹ and CO₂ uptake of 11.57 mmol g⁻¹ at 195 K.
