Crystal structure of 2-butyl­sulfanyl-4,6-bis­[(E)-4-(di­methyl­amino)­styr­yl]pyrimidine

In the title compound, C28H34N4S, the dihedral angles between the pyrimidine ring and the pendant 4-(di­methyl­amino)­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 inter­actions beyond van der Waals contacts occur in the crystal structure The title mol­ecule has a D–A–D structure, in which the pyrimidine ring is the electron-withdrawing part and the 4-(di­methyl­amino)­benzene rings are the electron-donating parts.
