Metal–organic framework

Uncommon card · No. 134672

Metal–organic frameworks (MOFs) are a class of coordination polymers built from metal nodes, discrete metal ions or metal-oxo clusters, commonly described as secondary building units (SBUs), joined by organic ligands to form one-, two-, or three-dimensional, typically porous frameworks. The ligands may be referred to as "struts" or "linkers", such as 1,4-benzenedicarboxylic acid (H2bdc). More formally, a metal–organic framework is a potentially porous extended structure made from metal ions and organic linkers. An extended structure is a structure whose sub-units occur in a constant ratio and are arranged in a repeating pattern. MOFs are a subclass of coordination networks, which is a coordination compound extending, through repeating entities, in one dimension, but with cross-links between two or more individual chains, loops, or spiro-links, or a coordination compound extending through repeating coordination entities in two or three dimensions. Coordination networks further belong to...
