Figure 2
The arrangement of the R₆⁶(32) building blocks in the crystal. Every molecule is connected to four others by N4—H1⋯N2ⁱ, N4—H2⋯N3ⁱⁱ, N2⋯H1ⁱⁱⁱ—N4ⁱⁱⁱ and N3⋯H2^iv—N4^iv hydrogen bonds. Adjacent molecules in chains running along the a axis [e.g. the molecule at (x, y, z) and the related molecule with symmetry code (i)] make a dihedral angle of 61°, whereas molecules at (x, y, z) and related molecules with symmetry codes (ii) and (iv) are coplanar. [Symmetry codes: (i) $[{1\over 2}]$ + x, −y, z; (ii) $[{3\over 2}]$ − x, 1 + y, − $[{1\over 2}]$ + z; (iii) $[{1\over 2}]$ + x, −y, z; (iv) $[{3\over 2}]$ − x, −1 + y, $[{1\over 2}]$ + z.]
