Figure 1
A view of the centrosymmetric hydrogen-bonded tetra­mer in the crystal structure of (I)[link], showing the atom-numbering scheme employed. The additional inter­molecular N—H⋯π inter­actions linking these tetra­mers into a two-dimensional network are not shown. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. [Symmetry code: (iii) −x, −y, 1 − z.]
