The crystalline salt of piperazine-1,4-diium (DL-)hydrogen malate (1:2), (C4H12N2)2+ (C4H5O5)2 −, has been prepared and characterized by X-ray crystallography. The title salt crystallizes in monoclinic space group P21/n with a = 7.073(1), b = 14.180(2), c = 7.526(1) Å, β = 94.66(1), V = 752.33(18) Å3 and Z = 2. Results indicate that the title salt exists as a racemic compound but a conglomerate. In the structure, axial and equatorial hydrogen atoms of piperiaine-1,4-diium are all involved in different bifurcated hydrogen bonds. The integral structure, formed by the hard hydrogen bonds of N–H⋅sO and O–H⋅sO, is stabilized further by soft hydrogen bond of C–H⋅sO.
