The mol-ecule of the title compound, C(8)H(6)N(4)S, is almost planar [maximum deviation from the mean plane = 0.020 (1) Å for the S atom]. In the crystal, a supra-molecular three-dimensional arrangement arises from N-H⋯N hydrogen bonds and weak aromatic stacking interactions along the a axis [centroid-centroid separation = 3.582 (2) Å].

There has been considerable recent interest in the ecosystem consequences of global and regional shifts in biogeochemical cycling and the loss of species diversity. Since biogeochemical cycling is the result of an interaction of numerous organisms, the link between diversity and biogeochemistry is a natural one. changes in either diversity or biogeochemiical &ling can dramatically influence one...

The title compound, C(17)H(14)ClN(7), crystallizes with two independent mol-ecules in the asymmetric unit. Inter-molecular N-H⋯N and C-H⋯N hydrogen bonds contribute to the stability of the crystal structure. In addition, weak C-H⋯π and π-π stacking [centroid-centroid distances of 3.699 (8) and 3.699 (6) Å] interactions are observed.
