摘要:

Crystals of difluoroboronN-methylacethydroxamate are monoclinic,a = 5.097(1),b = 10.653(2),c = 11.520(2) Å, β = 103.57(2)°,Z = 4, space groupP21/c. The structure was solved by direct methods and was refined by full-matrix least squares procedures to a finalRof 0.056 andRwof 0.077 for 988 reflections withI ≥ 3σ(I). The structure features a planar five-membered BO2CN ring. Bond lengths (corrected for libration) are: B—F, 1.374(3) and 1.381(3), O—B, 1.496(3) and 1.497(3), O—N, 1.349(2), O—C, 1.346(2), C—N, 1.298(3) and 1.458(3), and C—C, 1.468(3) Å.
