Figure 2
The nuclear density (yellow) arising from the 1.3 CD4 molecules per Cu (top row) in Cu3(btc)2 and the electron density (in yellow and blue) attributed to 1 bar of CH4 in Cu3(btc)2 obtained using TRDSE methods (bottom row) at 150 K (left) and 295 K (right). The densities are shown superimposed on one unit cell of Cu3(btc)2 viewed along [1, 0, 0]. Cu3(btc)2 is shown with Cu in blue (top) and orange (bottom), C in grey and O in red, and with H atoms omitted for clarity in all panels. Reprinted with permission from (top) Hulvey et al.
