2,3-Bis[(pyrimidin-2-ylsulfanyl)methyl]quinoxaline

Z.-C. Ma and H.-S. Xian

Abstract: In the title compound, C18H14N6S2, the two terminal pyrimidine groups attached to the central quinoxaline system adopt an anti conformation, with the thiopyrimidine groups on opposite sides of the quinoxaline plane. The dihedral angles formed by each of the two terminal pyrimidine and the central quinoxaline planes are 81.1 (3) and 82.0 (3)°, while the two pyrimidine planes are almost parallel to each other, forming a dihedral angle of 6.0 (3)°.
