Abstract
Herein, by replacement of the linear terephthalate linker with the bending 2,5-thiophenedicarboxylate (tdc2–) linker in the typical (3,9)-connected metal–organic framework, with a reduced 8-connected hydroxyl-centered trinuclear cluster, a new (3,8)-connected network, [Ni3(μ3-OH)(tdc)3(tpp)] [DZU-1; tpp = 2,4,6-tris(4-pyridyl)pyridine], was synthesized. The modified pore environment enables DZU-1 to selectively adsorb C2H2 over CO2 in an efficient manner.
