Infrared spectroscopy:A powder of M(bdc)(ted)0.5 2 mg)
was pressed onto a KBr pellet(~1 cm diameter,1-2 mm thick)
and placed into a high pressure high temperature cell purchased
from Specac (product number P/N 5850c) at the focal
point of the sample compartment of the infrared spectrometer
(Nicolet 6700,Thermo Scientific) equipped with a liquid N2–
cooled MCT-B detector.The cell was connected to a vacuum
line for evacuation.SO2 gas was introduced into the pressure
cell and all spectra were recorded in transmission between 400
and 4000 cm-1 (4 cm-1 spectral resolution).The pressure was
determined by calibrating the SO2 gas IR absorption at low
pressures (3 Torr) with a convection gauge (KJL 285801,
KurtJLeskerCo) and then using the integrated IR absorption to
determine the higher pressures since there is no dependence of
the internal mode dipole moment on pressure.
Adsorption isotherm:Measurements of SO2 uptake were
performed using a volumetric system specially constructed for
low-pressure experiments (see Figure S12).It comprises two
chambers,A and B,whose volumes have been determined
using helium.Chamber B is loaded with the sample and
chamber A is a gas reservoir.A known amount of powder
sample was placed in chamber B (volume = 4.134 cm3) with a
layer of glass wool on top to prevent sudden suction of the
powder sample.
