HKUST-1 (HKUST ⇒ Hong Kong University of Science and Technology), which is also called MOF-199, is a material in the class of metal-organic frameworks (MOFs). Metal-organic frameworks are crystalline materials, in which metals are linked by ligands (so-called linker molecules) to form repeating coordination motives extending in three dimensions. The HKUST-1 framework is built up of dimeric
