Deskripsi
In the title salt, C5H14N22+·2C4H3O4−, the asymmetric unit contains two independent 2-methylpiperazinium dications, which comprise a racemic pair, and four hydrogen maleate monoanions. In the roughly planar hydrogen maleate anions, intramolecular O—H...O hydrogen bonds generate S(7) rings. In the crystal, the four independent anions are linked to the 2-methylpiperazinium cations through N—H...O hydrogen bonds, forming two-dimensional layered structures lying parallel to (001).
