Abstract:
A new, highly porous acylamide-functionalized MOF with a (3,24)-connected rht-type network (HNUST-5) has been synthesized and structurally determined using powder X-ray diffraction. HNUST-5 exhibits a high BET surface area of 3643 m2 g-1, and a large CO2 uptake capability (38.9 mmol g-1 under 36 bar) with an excellent selectivity of CO2/CH4 (7.3) and CO2/N2 (32.5) at 273 K.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
