چکیده
The asymmetric unit of the title compound, C6H9N3, contains three crystallographically independent mol-ecules of similar geometry. All of the mol-ecules are almost planar, with r.m.s. deviations of 0.003, 0.016 and 0.005 Å. In the crystal, the mol-ecules are linked by N-H⋯N hydrogen bonds into zigzag ribbons parallel to the c axis, generating rings of R2(2)(8) graph-set motif.

The constituents of the title co-crystal, C(12)H(14)N(4)O(2)S·C(7)H(6)O(2), are connected by an eight-membered hetero-synthon {⋯NCNH⋯OCOH}, whereby the carb-oxy-lic acid forms donor and acceptor hydrogen bonds with a pyrimidine N atom and the adjacent amine, respectively. The dimeric aggregates thus formed are arranged in rows with their terminal NH(2) groups forming N-H⋯O hydrogen bonds with n...
