1,4-Bis(pyrimidin-2-yl-sulfanyl)-butane.


ABSTRACT: The -SCH(2)CH(2)CH(2)CH(2)S- portion of the title compound, C(12)H(14)N(2)S(2), adopts an extended zigzag conformation. The angles at the tetra-hedral carbon atoms are marginally increased [113.63?(12)° and 111.38?(17)° for S-C-C and C-C-C respectively] from the idealized tetra-hedral angle. The mol-ecule lies on an inversion center located at the mid-point of the butyl chain. In the crystal, there is a ?-? stacking inter-action between inversion-related pyrimidine rings with mean inter-planar spacing of 3.494?(2)?Å.

The angles at the tetra-hedral carbon atoms are marginally increased [113.63 (12)° and 111.38 (17)° for S-C-C and C-C-C respectively] from the idealized tetra-hedral angle. The mol-ecule lies on an inversion center located at the mid-point of the butyl chain.
