资源简介：
A novel 48.67 topology metal–organic
material (MOM) platform of formula [M(bpe)2(M′O4)] (M = Co or Ni; bpe = 1,2-bis(4-pyridyl)ethene; M′
= Mo or Cr) has been synthesized and evaluated in the context of gas
sorption. These MOMs have been assigned RCSR code mmo and are uninodal 6-connected nets. [Ni(bpe)2(MoO4)], MOOFOUR-1-Ni, and its chromate analogue, CROFOUR-1-Ni,
exhibit high CO2 affinity and selectivity, especially at
low loading. This behavior can be attributed to exceptionally high
isosteric heats of adsorption (Qst) of
CO2 in MOOFOUR-1-Ni and CROFOUR-1-Ni of ∼56 and
∼50 kJ/mol, respectively, at zero loading. These results were
validated by molecular simulations which indicate that the electrostatics
of these inorganic anions affords attractions toward CO2 that are comparable to those of unsaturated metal centers.
