Crystal structure of 8-ethoxy-3-(4-nitrophenyl)-2H-chromen-2-one
In the title compound, C(17)H(13)NO(5), the coumarin ring system is essentially planar (r.m.s. deviation = 0.008 Å). The nitrophenyl ring makes a dihedral angle of 25.27 (9)° with the coumarin ring plane. The nitro group is almost coplanar with the phenyl ring to which it is attached, making a dihe...
