85 g (0.06 mol) Sodium sulfate and 300 ml water was added into a 1000 ml three mouthed flask, mixed till the sodium sulfate dissolved, then a
of 18 g (0.11 mol) chloral hydrate was added. While stirring, the mixture of 12.7 g (0.1 mol) p-chloroaniline, 12 ml hydrochloric acid and 100 ml water was dropped to the reaction mixture causing white precipitation. Then 22 g (0.32 mol) hydroxylamine hydrochloride was added and the mixture was heated to 348 K. After 5 h, light yellow precipitation appeared, filtered and washed with water, dried and then added the yellow precipitation into concentrated sulfuric acid (50 ml) in batches at 353 K. Heated to 363 K and stirred for 30 minutes and dumped the mixture into ice water (1000 ml), stirred for 40 minutes, filtered and washed with water to neutral, dried and Yellow blocks of (I) were obtained by slow evaporation of an acetone solution (yield; 90%, m.p. 463 K).H atoms were positioned geometrically, with N—H = 0.86Å and C—H = 0.93Å and refined as riding with Uiso(H) = xUeq(C,O,N), where x = 1.5 for NH H and x = 1.2 for all other H atoms.

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. |
