چکیده
The title compound, C(10)H(10)N(8), resides on a crystallographic symmetry center and features an essentially planar mol-ecule [r.m.s. deviation = 0.278 (1) Å]. In the C=N-N=C fragment, the C=N distance is 1.3017 (18) Å and the N-N distance is 1.403 (2) Å. In the crystal, adjacent mol-ecules are linked by N-H⋯N hydrogen bonds into a three-dimensional network.
