Figure 3
Views of the intra- and inter­molecular C—H⋯π inter­actions in (I)[link], showing two different hydrogen-bonded chains, viz. (a) along the [100] direction (inter­actions are shown as dashed open lines) and (b) along the [110] direction (inter­actions are shown as dashed solid lines). The ErIII atoms labelled with the suffixes A, B, C, D and E are generated by the symmetry operations (−x + 1, −y + 1, −z + 1), (x − 1, y, z), (−x, −y + 1, −z + 1), (x − 1, y − 1, z) and (−x, −y, −z + 1), respectively. Only H atoms involved in the inter­actions are shown for clarity.
