Crystal structures of methyl 3,5-dibromo-4-cyanobenzoate and methyl 3,5-dibromo-4-isocyanobenzoate
The title crystals, C(9)H(5)Br(2)NO(2), are the first reported 2,6-dihalophenyl cyanide–isocyanide pair that have neither three- nor two-dimensional isomorphism. Both crystals contain contacts between the carbonyl O atom and a Br atom. In the crystal of the cyanide, R (2) (2)(10) inversion dimers fo...

description | The title crystals, C(9)H(5)Br(2)NO(2), are the first reported 2,6-dihalophenyl cyanide–isocyanide pair that have neither three- nor two-dimensional isomorphism. Both crystals contain contacts between the carbonyl O atom and a Br atom. In the crystal of the cyanide, R (2) (2)(10) inversion dimers form based on C≡N⋯Br contacts, a common packing feature in this series of crystals. In the isocyanide, the corresponding N≡C⋯Br contacts are not observed. Instead, the isocyano C atom forms contacts with the methoxy C atom. RNC was refined as a two-component pseudo-merohedral twin. |
