In the title compound, C16H23NO5, the H—N—O—C torsion angle is 98.6 (1)°, which is of a similar magnitude to other N,O-diacylhydroxylamines. The N—O distance is 1.4029 (14) Å, which is similar to the N—O distance in other N,O-diacylhydroxylamines. In the crystal, intermolecular N—H⋯O hydrogen bonds generate chains of molecules.

O-Adamantanecarboxoyl-N-4-methoxy-4-oxobutanoyl-hydroxylamine (I) was isolated from a methanol solution (14 ml) containing adamantane-1-carboxylate-2,5-pyrrolidinedione (0.25 g, 0.89 mmol) (Liu, et al., 2009) and NaOH (0.018 g, 0.45 mmol). The product was dried in vacuo; colourless crystals of I appeared after approximately 1 month from a 4.5 mg mL-1 solution of I in ethanol:water (7:3).
C and N bound-H (atoms were included in idealized positions and refined using a riding-model approximation, with C—H bond lengths fixed at 1.00 Å, 0.99 Å, 0.98 Å for methine, methylene and methyl H atoms respectively. N—H bond lengths fixed at 0.88 Å. Uiso(H) values were fixed at 1.2Ueq of the parent atoms for all H atoms except methyl H atoms for which 1.5Ueq of the parent atoms was used.

Experimental. The crystal was coated in Exxon Paratone N hydrocarbon oil and mounted on a thin mohair fibre attached to a copper pin. Upon mounting on the diffractometer, the crystal was quenched to 150(K) under a cold nitrogen gas stream supplied by an Oxford Cryosystems Cryostream and data were collected at this temperature. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

O-Adamantanecarboxoyl-N-4-methoxy-4-oxobutanoyl-hydroxylamine (I) (Fig 1.) was prepared in our laboratory as part of our program in understanding resonance and tautomerism in biologically relevant molecules such as N,O-diacylhydroxylamines and hydroxamic acids. The torsion angle defined by H—N—O—C in each of N,O-diacetylhydroxylamine (-99.0 (1) °), N-acetyl-O-benzoylhydroxylamine (-101.3 (1) °), and N-benzoyl-O-acetylhydroxylamine (-94.1 (1) °) is negative, which is distinct from the analogous angle in N,O-dibenzoylhydroxylamine determined by the same group, which is positive (99.7 (1) °) (Schraml et al., 2004). The positive torsion angle defined by H1—N1—O4—C6 in I is 98.6 (1) °, which is akin to N,O-dibenzoylhydroxylamine. The N—O distance in I (N1—O4 = 1.4029 (14) Å) is similar to the N—O distance in other N,O-diacylhydroxylamines as cited above. Intermolecular hydrogen bonds exist in I between respective amide groups, with H1···O3 = 1.87 Å (Table 1) forming an infinite one-dimensional polymer extending along the c-axis (Fig 2.).
