Abstract:
In the title compound, C19H19N3O2Se, the selenadiazole ring is roughly planar [maximum deviation 0.033 (6) Å]. The attached phenyl ring is twisted away at an angle of 47.5 (1)°. The butyl group is in an extended conformation [C-C-C-C torsion angle = 174.7 (2)°]. In the crystal, C-H⋯O inter-actions form C(10) chains running aling the c-axis direction.
