7596(2) Å, c = 15.0234(7) Å, α = γ = 90°, β = 92.771(4)°, V = 1427.25(10) Å3, Z = 4. The imide bond is twisted, and the O═C–N–C(O) units deviate significantly from planarity with dihedral angles around the imide group reaching ca. −150.3° (C1–N1–C2–O21 = −148.8° and C2–N1–C1–O11 = −151.9°). The nonplanarity of the imide moiety and the related conformational properties are discussed in a combined approach
