Crystal structure of 2-methyl-1H-imidazol-3-ium hydrogen oxalate dihydrate

Single crystals of the title mol­ecular salt, C(4)H(7)N(2) (+)·HC(2)O(4) (−)·2H(2)O, were isolated from the reaction of 2-methyl-1H-imidazole and oxalic acid in a 1:1 molar ratio in water. In the crystal, the cations and anions are positioned alternately along an infinite [010] ribbon and linked tog...

Sumario:Single crystals of the title mol­ecular salt, C(4)H(7)N(2) (+)·HC(2)O(4) (−)·2H(2)O, were isolated from the reaction of 2-methyl-1H-imidazole and oxalic acid in a 1:1 molar ratio in water. In the crystal, the cations and anions are positioned alternately along an infinite [010] ribbon and linked together through bifurcated N—H⋯(O,O) hydrogen bonds. The water mol­ecules of crystallization link the chains into (10-1) bilayers, with the methyl groups of the cations organized in an isotactic manner.
