title: Crystal structure of 4,6-bis-[(E)-4-bromo-styr-yl]-2-(butyl-sulfan-yl)pyrimidine.
abstract: In the title compound, C24H22Br2N2S, the dihedral angles between the central pyrimidine ring and the pendant bromo-benzene rings are 11.02 (11) and 13.20 (12)°. The butyl side chain adopts a gauche conformation [C-C-C-C = -67.4 (4)°]. In the crystal, weak aromatic π-π stacking is observed between the pyrimidine ring and one of the benzene rings [centroid-centroid separation = 3.6718 (17) Å].
