Crystal and Molecular Structure of (±)-7,7-(2′,2′-Dimethyl)pentamethylene-1-methyl-norbornane-2-oxime
Keyword(s):
Crystals of (±)-7,7-(2′,2′-dimethyl)pentamethylene-1-methyl-norbornane-2-oxime are monoclinic, a = 9.202(2), b = 12.852(3), c = 12.698(3) Å, β = 110.83(2)°, Z = 4, space group P21/c. The structure was solved by direct methods and was refined by full-matrix least-squares procedures to a final R of 0.048 for 1538 reflections with I ≥ 3σ(I). The crystal structure consists of pairs of molecules linked by N … H—O hydrogen bonds (N … O = 2.821(3) Å ) to form centrosymmetric dimers. Bond distances are as follows: C—N = 1.266(3), N—O = 1.426(3), mean C(sp3)—C(sp3) = 1.540, and mean C(sp3)—C(sp3) = 1.511 Å.
