Tris(1,10-phenanthroline)sodium 2,4,6-trimercapto-1,3,5-triazin-1-ide

The title compound, [Na(C₁₂H₈N₂)₃](C₃H₂N₃S₃), contains an Na⁺ centre which is ionicly bonded to three 1,10-phenanthroline (phen) ligands and one tri­thio­cyanurate(1−) (ttcH₂) anion. In the crystal structure, the anions are linked via hydrogen bonds to form linear chains. The S and H atoms of the ttcH₂ anion participate in intermolecular N—H⋯S hydrogen bonding, with N⋯S distances of 3.298 (2) and 3.336 (2) Å. The phen ligands are almost parallel, with dihedral angles of 3.92 (5), 11.75 (5) and 15.45 (5)°; moreover, they are nearly perpendicular to the ttcH₂ chains, with angles of 81.94 (7), 85.86 (7) and 85.96 (7)°.
