Answer the following about early work on metal-organic frameworks by the three winners of the 2025 Nobel Prize in Chemistry, for 10 points each.
[10e] In the 1990s, Richard Robson experimented with coordination via tetra- examples of this functional group, which consists of a carbon triple-bonded to a nitrogen.
ANSWER: nitriles [accept cyanide or cyano groups]
[10m] In 1997, Susumu Kitagawa demonstrated a novel structure in which 4,4-bipyridine and nitrate groups coordinate to the metal center via this geometry. AX7E0 compounds like IF7 have this molecular geometry.
ANSWER: pentagonal bipyramidal
[10h] In 1999, Omar Yaghi’s lab pioneered framework synthesis by coordinating BDC ligands to four atoms of this metal, clusters of which are the basis of many MOFs with high internal surface area such as DUT-60.
