In the crystal structure of the title compound, C4H7N4O+-
Cl2H2O, adjacent cations are connected to one another
through N—H O hydrogen bonds, forming infinite chains
along the b axis. These chains are further hydrogen bonded to
the chloride anions and water molecules, resulting in a threedimensional
network. The pyrimidine rings of adjacent
molecules are arranged in an antiparallel manner above each
other with centroid–centroid distances of 3.435 (1) A ° , indicative
of – interactions.
