Abstract

In the title compound, C11H12N4O5.C2H6OS, the molecular components are linked by a short hydrogen bond with dimensions O . . . O 2.517 (2) Angstrom and O--H . . . O 168 degrees. Paired C--H . . . O hydrogen bonds [C . . .O 3.362 (2) and 3.382 (2)Angstrom; C--H . . . O 157 and 140 degrees] generate cyclic centrosymmetric four-component aggregates reinforced by aromatic pi-pi -stacking interactions, and further C--H . . . O hydrogen bonds [C . . . O 3.472 (3) and 3.521 (2) Angstrom; C--H . . . O 156 and 157 degrees] link these aggregates into chains.
