title: Crystal structure of 2-butyl-sulfanyl-4,6-bis-[(E)-4-(di-methyl-amino)-styr-yl]pyrimidine.
abstract: In the title compound, C28H34N4S, the dihedral angles between the pyrimidine ring and the pendant 4-(di-methyl-amino)-benzene rings are 14.20 (5) and 14.56 (4)°. The butyl side chain adopts an anti conformation [C-C-C-C = -171.53 (13)°]. No directional inter-actions beyond van der Waals contacts occur in the crystal structure The title mol-ecule has a D-A-D structure, in which the pyrimidine ring is the electron-withdrawing part and the 4-(di-methyl-amino)-benzene rings are the electron-donating parts.
