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 the hydrazino groups and the N atoms of the pyrimidine rings of both types of the mol-ecules, linking the mol-ecules into a C(7) graph-set motif along . The methyl groups and the N atoms of the pyrazole rings form weak C - H⋯N hydrogen bonds, which connect chains of the dimers in a C(4) motif parallel to . © 2009 Dolzhenko et al.||Source Title:||Acta Crystallographica Section E: Structure Reports Online||URI:||http://scholarbank.nus.edu.sg/handle/10635/92915||ISSN:||16005368||DOI:||10.1107/S1600536809023952|
