3,5-Dimethyl­pyrazolium 3,5-dinitro­salicylate

In the title mol­ecular salt, C(5)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (−), the roughly planar anion (r.m.s. deviation = 0.120 Å) has been deprotonated at the phenol group. An intra­molecular O—H⋯O hydrogen bond in the anion generates an S(6) ring. In the crystal, the components are linked by cation-to-ani...

Sumario:In the title mol­ecular salt, C(5)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (−), the roughly planar anion (r.m.s. deviation = 0.120 Å) has been deprotonated at the phenol group. An intra­molecular O—H⋯O hydrogen bond in the anion generates an S(6) ring. In the crystal, the components are linked by cation-to-anion N—H⋯O and N—H⋯(O,O) hydrogen bonds, generating [010] double chains. Weak C—H⋯O inter­actions consolidate the packing.
