4-Bromo­methyl-7-methyl-6,8-dinitro­coumarin

The crystal structure of the title compound, C(11)H(7)BrN(2)O(6), establishes the substitution positions of the nitro groups from the nitration reaction of 7-methyl-4-bromo­methyl coumarin. The mean planes of the nitro groups form dihedral angles of 43.9 (8) and 52.7 (10)° with the essentially plana...

description The crystal structure of the title compound, C(11)H(7)BrN(2)O(6), establishes the substitution positions of the nitro groups from the nitration reaction of 7-methyl-4-bromo­methyl coumarin. The mean planes of the nitro groups form dihedral angles of 43.9 (8) and 52.7 (10)° with the essentially planar [maximum deviation 0.031 (6) Å] benzopyran ring system.
