Table 3. Dihedral angles (°).
θA–C is the dihedral angle between the mean planes of the chromene and phenyl ring and the thiazole ring. θA–B is the dihedral angles between the mean planes of the chromone ring and the plane defined by the O2/C21/N2 atoms. θB–C is the dihedral angle between the mean planes of the thiazole ring and the plane defined by the O3/C41/N3 atoms.
