Crystal structure of 4-bromo­phenyl-2-oxo-2H-chromene-3-carboxyl­ate

In the title compound, C(16)H(9)BrO(4), the coumarin ring system is approximately planar, with an r.m.s deviation of the ten fitted non-H atoms of 0.031 Å, and forms a dihedral angle of 25.85 (10)° with the bromo­benzene ring. The carbonyl atoms are syn. In the crystal, mol­ecules are connected alon...

Sumario:In the title compound, C(16)H(9)BrO(4), the coumarin ring system is approximately planar, with an r.m.s deviation of the ten fitted non-H atoms of 0.031 Å, and forms a dihedral angle of 25.85 (10)° with the bromo­benzene ring. The carbonyl atoms are syn. In the crystal, mol­ecules are connected along [001] via C—H⋯O inter­actions, forming C(6) chains. Neighbouring C(6) chains are connected via several π–π inter­actions [range of centroid–centroid distances = 3.7254 (15)–3.7716 (16) Å], leading to sheets propagating in the bc plane.
