What does the boss UiO-66 look like?

 “MOFIA”, what is that?

It is just a nickname for the scientific community working on Metal Organic Frameworks, acronymed MOFs, thus the community is the MOFIA.

The boss of the crown family, namely the UiO-66, is “probably” the most famous MOF of these past 6 years, now taking care of the family over the HKUST-11 and MOF-52. This solid has been reported by Cavka et al. in 20083 and has generated quite a lot of enthusiasm from the ‘Mofia’. There is probably UiO-66 in each lab around the world working on MOFs.

This MOF was basically the first built up from a tetravalent metal, the zirconium Zr4+ and thus an novel inorganic cluster (see below), which has given rise to a robust solid, i.e. much more stable than most of known MOFs. Indeed, it has been shown that, in general, by increasing the valence of the metal, the chemical and thermal stabilities of MOF increases.4 The linker is the terephthalate.

Where did the structure come from?

The structure comes from a paper of Cavka et al. published in the Journal of American Chemistry in 2008.3
