Ethyl 2,6-bis­(4-bromo­phen­yl)-1-iso­cyano-4-oxo­cyclo­hexa­necarboxyl­ate

In the title compound, C₂₂H₁₉Br₂NO₃, the central oxo­cyclo­hexane ring is in a twist-boat conformation; all the substituents (one eth­oxy­carbonyl and two aryl groups) are located in equatorial orientations. One of the –CH₂– groups and the opposite –CH– group bearing a bromo­benzene substituent form the flagpoles of the twist-boat. The dihedral angle between the aromatic rings is 76.4 (4)°. In the crystal, weak C—H...O inter­actions link the mol­ecules into C(5) chains propagating in the [010] direction. A short Br...O contact of 3.254 (4) Å is observed.
