Crystal structure, thermal analysis, and IR spectrometric investigation of 1,2-diammonium-2-methyl propane sulfate monohydrate

Chemical preparation, X-ray single crystal, thermal analysis, and IR spectrometric investigation of C₄H₁₄N₂SO₄·H₂O (denoted DAMPS) are described. DAMPS crystallizes in the orthorhombic system with P2₁2₁2₁ space group, a = 9.2726(4) Å, b = 9.5227(2) Å, c = 10.3807(4) Å, V = 916.62(6) ų, and Z = 4. The DAMPS structure is built up from inorganic chains parallel to the b axis and linked via Ow–H···O hydrogen bonds. These chains are interconnected by organic groups so as to build a three-dimensional arrangement.
