(Received 28 May 2008; accepted 29 May 2008; online 7 June 2008)

In the title mol­ecule, C26H28N2O3, the piperidine ring adopts a chair conformation. The two methoxy­phenyl groups attached to the piperidine ring at positions 2 and 6 have equatorial orientations, and make a dihedral angle of 80.72 (15)°. The benzyl group at position 3 has an equatorial orientation. The oxime group at position 4 has a bi­sectional orientation. The ring of the benzyl group makes dihedral angles of 64.71 (16) and 84.79 (17)° with the two benzene rings. Mol­ecules are linked by inter­molecular N—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds, and C—H⋯π inter­actions. There is also a C—H⋯O intra­molecular inter­action.

Comment top

In a wide research program toward new and efficient antimicrobial agents, a series of t3-benzyl-r2,c6-diarylpiperidin-4-ones have been synthesized and tested for their in vitro antibacterial and antifungal activities (Jayabharathi et al., 2007). Thiruvalluvar et al. (2007) have reported the crystal structure of t3-benzyl-1-formyl-r2,c-6-diphenylpiperidin-4-one, in which the piperidine ring is in a distorted boat form.

In the title compound, (Fig. 1), the piperidine ring adopts a chair conformation. The two methoxyphenyl groups attached to the piperidine ring at positions 2 and 6 have equatorial orientations, and make a dihedral angle of 80.72 (15)°. The benzyl group at position 3 has an equatorial orientation. The oxime group at position 4 has a bisectional orientation. The phenyl ring of the benzyl group makes a dihedral angle of 64.71 (16)° with the benzene ring at C2, and 84.79 (17)° with the benzene ring at C6. Molecules are linked by intermolecular N1—H1···O6, O4—H4···N1 and C65—H65···O4 hydrogen bonds (Fig. 2). There are C12—H12B···π (-1 + x, y, z) interactions involving the phenyl ring at C13 and C16—H16A···π (1 - x, 1 - y, -z) interactions involving the benzene ring at C2. There is also a C5—H5A···O4 intramolecular interaction.

Experimental top

The title compound was prepared according to the literature procedure (Jayabharathi et al., 2007). t3-Benzyl-r2,c6-bis(p-methoxyphenyl)piperidin-4-one (ca 0.05 mol, 20 g) and sodium acetate trihydrate (0.15 mol, 20.41 g) were dissolved in boiling ethanol and hydroxylamine hydrochloride (0.06 mol, 4.17 g) was added. The mixture was heated to 313 K and stirred for 3-4 h. It was allowed to stand overnight and then poured into crushed ice. The separated solid was filtered off and recrystallized from ethanol. The yield of the isolated pure product was 16 g (80%).

Refinement top

The H atom bonded to N1 was located in a difference Fourier map and refined isotropically to an N—H bond length of 0.97 (3) Å. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.95–1.00 Å and O—H = 0.84 Å; Uiso(H) = xUeq(carrier atom), where x = 1.5 for methyl and O, 1.2 for all others.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
