(Received 11 October 2008; accepted 18 October 2008; online 25 October 2008)

In the title compound, C13H16FNO, the fluoro­benzene ring plane and the plane through the amide unit are inclined at a dihedral angle of 29.92 (7)°. The cyclo­hexane ring adopts a chair conformation. In the crystal structure, N—H⋯O hydrogen bonds, augmented by weak C—H⋯O inter­actions, link the mol­ecules into transverse chains along a. These chains are linked into zigzag columns down a by C—H⋯F hydrogen bonds and C—H⋯π inter­actions.

Comment top

The background to this study has been described in our earlier paper reporting the structure of 4-chloro-N-(3-methoxyphenyl)-benzamide (Saeed et al. 2008).

We report here the structure of the title 2-fluorobenzamide derivative, I, Fig 1. The C2—C1—O1—N1—C8 unit is planar with a maximum deviation of 0.0223 (10) Å. This plane makes a dihedral angle of 29.92 (7) ° with the fluorobenzene ring plane. The N-cyclohexyl ring adopts a chair conformation with Cremer-Pople puckering parameters Q(2)= 0.0138 (15) Å, ϕ(2) = 23 (2)° and Q(3) = 0.5763 (15)Å (Cremer & Pople, 1975). 2-fluorobenzamide derivatives with aliphatic substituents on the amide N atom are unusual with only one reasonably comparable derivative (Kobal et al. 1990) of the Cambridge Structural Database V5.29 (Allen, 2002). In contrast, N-aryl derivatives are more common and the salient bond distances and angles in the present molecule agree well with those reported previously (see for example Chopra & Guru Row, 2008; Donnelly et al., 2008; Hou et al., 2004).

In the crystal structure, chains are formed that run in opposite directions along a through N—H···O hydrogen bonds, Table 1, Fig 2. These interactions are supported by weak C9—H9B···O1 hydrogen bonds. Additional weak C—H···F hydrogen bonds and C—H···π interactions link these chains into zigzag columns down a Fig. 3.

Experimental top

2-Fluorobenzoyl chloride (1 mmol) in CHCl3 was treated with cyclohexyl amine (3.5 mmol) under a nitrogen atmosphere at reflux for 5 h. Upon cooling, the reaction mixture was diluted with CHCl3 and washed consecutively with 1 M aq HCl and saturated aq NaHCO3. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. Crystallization of the residue from CHCl3 afforded the title compound (79%) as white needles: Anal. calcd. for C13H16FNO: C 70.56, H 7.29, N 6.33%; found: C 70.08, H 7.31, N 6.38%.

Refinement top

The H atom bound to N1 was located in a difference electron density map and refined freely with an isotropic displacememt parameter. All other H-atoms were refined using a riding model with d(C—H) = 0.95 Å, Uiso= 1.2Ueq (C) for aromatic and 0.98 Å, Uiso = 1.5Ueq (C) for CH3 H atoms. In the absence of significant anomalous dispersion effects, Friedel pairs were averaged.

Special details top

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.
