Figure 2
Top: View along the a axis of one sheet. Hydrogen bonds from cations above and below the sheet are shown. Bottom: Projection down the b axis, showing the sheets stacked perpendicular to the a axis, and the hydrogen bonds linking the sheets together. (Scale is slightly larger than in the top diagram.) The chains of hydrogen bonds along the [102] direction are evident. Cu atoms are colored red, N atoms blue, and C and NH atoms black. H atoms of the C2H5 gropu are not shown, and only one orientation for each of the disordered CN groups is drawn. |
