Abstract top

In the title compound, C12H10O4, the five-membered ring adopts an envelope conformation, with the Csp3 atom at the flap [deviation = 0.145 (2) Å]. In the crystal structure, molecules are linked by intermolecular O-H...O and C-H...O hydrogen bonds, forming a three-dimensional network.

Comment top

Ninhydrin is used to detect α-amino acids, proteins and dipeptides. When it reacts with free amines, a deep blue or purple colour known as Ruhemann's purple (RP) is evolved (Ruhemann, 1910). Ninhydrin is also used to monitor deprotection in solid phase peptide synthesis (Kaiser Test) (Kaiser et al., 1970). It is one of the most widely used reagents for chemical development of fingerprints on porous surfaces. We herein present the crystal structure of the title compound, a derivative of ninhydrin.

Bond lengths (Allen et al., 1987) and angles in the title molecule (Fig. 1) are within normal ranges. The indan ring system (C1-C9) is almost planar, with a maximum deviation of 0.072 (1) Å for atom C9 while the dihedral angle formed by the benzene ring and the five-membered ring is 1.87 (8)°. The keto atom O1 lies 0.075 (2) Å from the indan plane whereas the keto atom O2 is displaced from the C1-C9 plane by 0.184 (2) Å. The five-membered ring adopts an envelope conformation, with atom C9 at the flap [deviation 0.145 (2) Å]. The C2—C1—C9—O3 torsion angle is 103.16 (14) Å.

In the crystal structure (Fig. 2), the molecules are linked by intermolecular O3—H1O3···O2 and C3—H3A···O4 hydrogen bonds (Table 1) into a two-dimensional network parallel to the (100). The adjacent networks are linked via C12—H12A···O4 hydrogen bonds to form a three-dimensional network.

Experimental top

The title compound was synthesized by the reaction of ninhydrin (1.78 g), trichloroacetic acid (1.64 g) and catalytic amount of magnesium in presence of acetone. Ninhydrin and tricholoro acetic acid in molar ratio 1:1 were allowed to reflux with acetone in presence of Mg turnings for 1 h. The reaction mixture was dried under reduced pressure and was purified by chromatography over silica gel column. Elution of the column with petroleum ether-diethyl ether (4:1) followed by crystallization with petroleum ether-chloroform (1:1) afforded fine crystals of the title compound (120 mg, m.p. 399 K).

Refinement top

Atom H1O3 was located in a difference Fourier map and refined freely. The remaining H atoms were positioned geometrically and refined using a riding model, with C-H = 0.93–0.97 Å and Uiso(H) = 1.2 and 1.5 Ueq(C). A rotating-group model was applied for the methyl group. In the absence of significant anomalous dispersion, 1513 Friedel pairs were merged for the final refinement.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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.
