Crystal structure of 2-methyl-piperazine-1,4-diium bis-(hydrogen maleate).


ABSTRACT: In the title salt, C5H14N2 (2+)·2C4H3O4 (-), the asymmetric unit contains two independent 2-methyl-piperazinium dications, which comprise a racemic pair, and four hydrogen maleate monoanions. In the roughly planar hydrogen maleate anions, intra-molecular O-H?O hydrogen bonds generate S(7) rings. In the crystal, the four independent anions are linked to the 2-methyl-piperazinium cations through N-H?O hydrogen bonds, forming two-dimensional layered structures lying parallel to (001).
