چکیده
In the crystal of the title compound, C(5)H(8)N(4), centrosymmetric dimers are linked by pairs of N-H⋯N hydrogen bonds. Further N-H⋯N links result in a two-dimensional array whereby wave-like supra-molecular chains are inter-connected by R(2) (2)(8) ring motifs.

The title compound, C(35)H(30)N(2)S(3), has been synthesized by a solvent-free reaction. The mol-ecule exhibits an E,E configuration, the benzene rings and pyrimidine rings being located on the opposite sides of the C=C bonds. The centroid-centroid separation of 3.5808 (17) Å indicates the existence of π-π stacking between nearly parallel pyrimidine and benzene rings of adjacent mol-ecules.

The title compound, C(6)H(8)N(6), crystallizes as an N-H⋯N hydrogen-bond-linked dimer of two almost identical mol-ecules in the asymmetric unit. Both of the mol-ecules are almost planar (rms deviations of 0.0186 and 0.0296 Å in the two molecules) and their hydrazino groups are turned towards the pyrazole rings. The dimers are arranged into chains via inter-molecular N-H⋯N hydrogen bonds between...
