The compound was synthesised using a literature method (Zalipsky et al., 1983) with some modification. Colourless plate-like crystals suitable for X-ray analysis were obtained by crystallization from ethanol. Overall yield: 71%. M.p.: 445 K (EtOH).
H atoms were positioned geometrically and treated using a riding model, with bond lengths 0.96, 0.97, 0.98 and 0.93 Å for CH3, CH2, CH and CH (aromatic), respectively. H atoms bound to the N and O atoms were located in difference maps and refined with DFIX restraints N—H = 0.87 (3) Å and O—H = 0.82 (2) Å. The displacement parameters of the H atoms bound to C were constrained with Uiso(H) = 1.2 (aromatic, methylene or methine C) or 1.5Ueq (methyl C).
It is well known that 3-substituted cyclobutane carboxylic acid derivatives exhibit anti-inflammatory and anti-depressant activity (Dehmlow & Schmidt, 1990), and also
properties (Coghi, et al., 1976).The structure of (I) (Fig. 1) contains two cyclobutane rings (C7—C10),(C16—C19) each with methyl and phenyl substituents in the 3-position. The four-membered rings are linked by a C12,C13,N1,C14,C15 bridge. The best fit meanplanes through the (C7—C10) and (C16—C19) atoms of the cyclobutane rings subtend dihedral angles of 36.69 (24)°, 41.91 (21)° with the planes of the (C1—C6) and (C21—C26) phenyl rings respectively.
Values for the puckering of the cyclobutane has been reported as 23.5-24.3° (Swenson et al.. 1997, Allen, 1984). In this molecule the C7—C8—C9 plane forms a dihedral angle of 25.83 (43)° with the C9—C10—C7 plane and the angle between the C16—C17—C18 and C18—C19—C16 planes is 26.74 (36)°.

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. |

It is well known that 3-substituted cyclobutane carboxylic acid derivatives exhibit anti-inflammatory and anti-depressant activity (Dehmlow & Schmidt, 1990), and also liquid crystal properties (Coghi, et al., 1976).
The structure of (I) (Fig. 1) contains two cyclobutane rings (C7—C10),(C16—C19) each with methyl and phenyl substituents in the 3-position. The four-membered rings are linked by a C12,C13,N1,C14,C15 bridge. The best fit meanplanes through the (C7—C10) and (C16—C19) atoms of the cyclobutane rings subtend dihedral angles of 36.69 (24)°, 41.91 (21)° with the planes of the (C1—C6) and (C21—C26) phenyl rings respectively.
Values for the puckering of the cyclobutane has been reported as 23.5-24.3° (Swenson et al.. 1997, Allen, 1984). In this molecule the C7—C8—C9 plane forms a dihedral angle of 25.83 (43)° with the C9—C10—C7 plane and the angle between the C16—C17—C18 and C18—C19—C16 planes is 26.74 (36)°.
In the crystal structure N—H···O, O—H···N and C—H···π interactions stabilize the packing, Table 2, and link the molecules into infinite chains, Fig.2, Fig. 3.
