Abstract: In the title spiro compound, C29H24N4S, the quinoxaline and thiadiazole ring systems share a common C atom; their mean planes are aligned at 87.0 (1)° in one molecule and at 84.1 (1)° in the other independent molecule. The thiazole ring possesses two aromatic ring substituents and is roughly coplanar with these rings [the dihedral angles between the thiadiazole and phenyl rings are 10.7 (1) and 11.7 (1)° in one molecule, and 16.8 (1) and 17.7 (1)° in the other]. The aromatic ring of the benzyl unit of one molecule is disordered over two orientations in a 1:1 ratio.
