The title compound, C 30 H 18 N 8 Á2H 2 O, is a solvate of 2,3,7,8tetra(pyridin-2-yl)pyrazino[2,3-g]quinoxaline and, like the latter, is crystallographically centrosymmetric. The pyrazine ring makes dihedral angles of 54.95 (6) and 28.09 (6) with the two independent pyridine rings. The two pyridine
