title: Crystal structure of 4-methyl-sulfanyl-2-phenyl-quinazoline.
abstract: In the title compound, C15H12N2S, the methylthioquinazoline group is planar with the methyl C displaced by only 0.116 (3) Å from the plane of the quinazoline moiety. The dihedral angle between the phenyl ring and the quinazoline ring system is 13.95 (5)°. In the crystal, each molecule is linked by π-π stacking between to two adjacent inversion-related molecules. On one side, the inverted quinazoline groups interact with a centroid-centroid distance of 3.7105 (9) Å. On the other side, the quinazoline group interacts with the pyrimidine and phenyl rings of the second neighbour with centroid-centroid distances of 3.5287 (8) and 3.8601 (9) Å, respectively.
