Fluoren-9-one oxime
In the title mol-ecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intra-molecular C-H⋯O generates an S(6) ring. In the crystal, mol-ecules related by a twofold screw axis are connected by O-H⋯N hydrogen bonds, forming [100] chains Within these chains, m...
متن کامل(E)-4-Phenylbutan-2-one oxime
In the title compound, C(10)H(13)NO, the C-C-C-C torsion angle formed between the benzene ring and the butan-2-one oxime unit is 73.7 (2)°, with the latter lying above the plane through the benzene ring. In the crystal, inter-molecular O-H⋯N hydrogen bonds link pairs of mol-ecules into dimers, forming R(2) (2)(6) ring motifs which are stacked along the a axis.
متن کامل(E)-17β,19-Epoxymethano-17,23,24-tridemethyl-4-nor-5β,18α-olean-3-one oxime
In the penta-cyclic triterpenoide skeleton of the title mol-ecule, C(27)H(43)NO(2) [systematic name: (3E,3aS,5aR,5bR,7aR,11R,11aR,11bR,13aR,13bR)-5a,5b,10,10,13b-penta-methyl-icosa-hydro-1H-11,7a-(epoxy-methano)cyclo-penta-[a]chrysen-3-one oxime], the five-membered ring A has an envelope conformation, while the six-membered rings B-E adopt chair conformations. Rings A and B are cis-fused. The h...
متن کاملBenzamide oxime
In the crystal structure of the title compound, C(7)H(8)N(2)O, mol-ecules are connected via inter-molecular N-H⋯O and O-H⋯N hydrogen bonds to form a two-dimensional supra-molecular structure. The oxime group has an E configuration and the dihedral angle between the mean planes of the benzene ring and the amidoxime grouping is 20.2 (3)°.
متن کامل2,6-Dichlorobenzaldehyde oxime
In the title compound, C(7)H(5)Cl(2)NO, there are two mol-ecules in the asymmetric unit. The mol-ecules are essentially identical. Each mol-ecule is connected to a symmetry-related mol-ecule through an inversion center by O-H⋯N hydrogen bonds, building an R(2) (2)(6) graph-set motif.
