چکیده
The title thio-uracil derivative, C(9)H(11)N(3)OS, exists in the thione form. The six atoms comprising the ring are almost coplanar [r.m.s. deviation = 0.015 Å] and the 2-methyl-propyl group lies approximately perpendicular to this plane [the N-C-C-C torsion angle is 72.88 (14)°]. Linear supra-molecular chains along [001] sustained by N-H⋯O and N-H⋯S hydrogen bonding feature in the crystal packing.
