High pressure single crystal X-ray diffraction measurements have been performed over
the 0-2.5 GPa pressure range with the 3D metal-organic hybrid material
{[Cu(CO3)2](CH6N3)2}n (1). This metal-organic framework material contracts over the 0-4
GPa pressure range, but exhibits reversible softening at pressures in excess of 2.5 GPa. An
extensive evaluation of the elastic properties of 1 has been performed, and the room
temperature isothermal bulk modulus for 1 is 34.5(4) GPa, which indicates that it has
structural strength comparable to that of zeolitic materials. Furthermore, the structural
rearrangement mechanics that occur in 1 in response to pressure, and their relation to the
elastic properties, will be presented.
