The asymmetric unit of the title compound, C18H29NO3, contains two independent mol­ecules. The benzene ring and the mean plane of the alkyl unit form dihedral angles of 83.69 (12) and 77.14 (11)° in the two mol­ecules. In the crystal structure, weak C—H⋯O hydrogen bonds link mol­ecules into double-layer ribbons extending in [110].

Comment top

Nitrobenzene and its derivatives are of great interest for their various applications. Recently, we reported the crystal structure of 1-decyloxy-4-nitrobenzene (Yue, 2009). As an extension of our work on the structure characterizations of nitrobenzene derivatives, we report herein the crystal structure of the title compound.

The title compound, as shown in Fig. 1, comprises two independent molecules in the asymmetric unit. Two benzene rings of the two molecules form a dihedral angle of 48.12 (13) °. Weak C—H···O hydrogen bonds (Table 1) link molecules into ribbons extended in direction [110].

Experimental top

4-Nitrophenol (0.14 g, 1 mmol) and dodecyl iodide (0.30 g, 1 mmol) were dissovled in 15 ml of acetone. The sodium hydroxide solution (10 ml, 8%) was added into the above solution. The resultant mixture was heated for 2 h under refluxing and then the solution was cooled to room temperaure in an ice bath with stirring. The colourless crystals suitable for single-crystal analysis were obtained by recrystallization from 95% ethanol.

Refinement top

H atoms were placed in calculated positions (C—H 0.93-0.97 Å) and were included in the refinement in the riding model with Uiso(H) = 1.2 or 1.5 Ueq(C).

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.
