Figure 5
A packing diagram for (I)[link], viewed down the c axis, showing the centrosymmetric tetra­mer R44(18) ring motif. Hydrogen bonds are shown as dashed lines. H atoms not involved in hydrogen bonding and the minor components of disordered atoms C131/O21/C141 have been omitted for clarity. Only atoms involved in hydrogen bonding are labelled. [Symmetry codes: (i) −x + 2, −y + 1, −z + 2; (ii) x + 1, y, z.]
