An unprecedented (3, 4)-connected self-penetrating metal-organic framework

We present here a new flexible, acylamide ligand to construct (3, 4)-connected net. The resultant presents a previously unobserved topology matrix featuring (6 · 82)(6 · 85)(62 · 10)(62 · 83 · 10) topology symbol. Moreover, the self-penetrating structure and the potential porosity in 1 is still notable.
