The stacking in [Cu(CA)(phen)]n (Molčanov et al., 2014bBB56). (a) A polymeric chain with a long Cu—O bond indicated by a blue arrow. (b) The electrostatic potential plotted onto a Hirshfeld surface. It is apparent that there is close contact between the electron-rich (red) and electron-poor (blue) regions. (c) The molecular surface represented as VDP. The face corresponding to the elongated Cu—O bond is highlighted in yellow.
