A new organic sulfate (C8H22N2)SO42H2O denoted DPAES is obtained by interaction of H2SO4 with the organic molecule 2-[Diisopropylamino] ethylamine. We describe its crystallographic and structural features. DPAES is triclinic, Pī, with the lattice parameters a = 6.8841(2)?, b = 8.4966(2)?, c = 12.0804(3)?, = 81.824(1)o, = 88.007(1)o, = 78.649(1)o, V = 685.72(3)?3, and Z = 2. Its atomic arrangement is described as inorganic chains of SO42- units and water molecules, these chains are interconnected by organic groups so as to build layers parallel to the (001) planes. The IR data of DPAES are reported and discussed according to the theoretical group analysis and by comparison with IR results of similar compounds. The coupled TG-DTA thermal study shows the departure of two water molecule, con- firming the hydrated character of this compound.
