The asymmetric unit of the title compound, C12H9N2+·ClO4-·C6H6N4O·2H2O, contains a monoprotonated 4,7-phenanthrolinium (47phen) cation, a perchlorate anion balancing its charge, a neutral molecule of 5-methyl-1,2,4-triazolo[1,5-a]pyrimidin-7(4H)-one (HmtpO) and two interstitial water molecules. In the crystal structure, the acidic H atoms of 47phenH+ and HmtpO form strong hydrogen bonds with the water molecules, which in turn act as hydrogen-bond donors, forming links between them and towards the carbonyl O atom of HmtpO, the non-protonated N atom of 47phen+ and one of the O atoms of the anion.
