In the title hydrated molecular salt, [Fe(C12H8N2)3](C9H5N4O)2·0.5H2O, the water molecule site is half-occupied. The Fe—N bond lengths within the octahedral tris-chelate [Fe(phen)3]2+ ion (phen is 1,10-phenantroline) are indicative of a low-spin d6 electronic configuration for the metal ion. The C—N, C—C and C—O bond lengths in the polynitrile anions indicate extensive electronic delocalization. In the crystal, the components are linked through O—H...N hydrogen bonds, forming [100] chains, as well as through Coulombic interactions.
