Crystal structure of 2-methyl­piperazine-1,4-diium bis­(hydrogen maleate)

In the title salt, C(5)H(14)N(2) (2+)·2C(4)H(3)O(4) (−), 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...

description In the title salt, C(5)H(14)N(2) (2+)·2C(4)H(3)O(4) (−), 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).
