In the indane ring system of the title molecule, C13H12O4, the hydroxy-bearing C atom is 0.134 (1) Å out of the plane of the remaining essentially planar atoms (r.m.s. deviation = 0.010 Å). In the crystal, molecules are linked into chains along the b axis by intermolecular O—H⋯O hydrogen bonds. Additional stabilization is provided by weak intermolecular C—H⋯O hydrogen bonds.

A mixture of ninhydrin (1.78 g) and ethylmethyl ketome (0.90 ml) in molar ratio 1:1 were heated on water bath for 15 minutes in presence of acetic acid. The reaction mixture was dried on rotatory evaporator at low pressure and crystallized with chloroform-n-hexane (1:1) to give the colorless crystals of the title compound (Yield: 100%, mp. 406–408 K).
The O-bound hydrogen atom was located in a difference Fourier map and refined freely. The rest of the hydrogen atoms were positioned geometrically [C–H = 0.93–0.98 Å] and refined using a riding model, with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating-group model was applied for methyl groups.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems 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. |

In the continuation of our studies of ninhydrin reactions with acetone in acidic medium (Fun et al., 2009), we report herein the structure of the title compound (Fig. 1) formed by the reaction of ninhydrin with ethylmethyl ketone in acetic acid. The title compound has potential as a starting material for the synthesis of a large number of complex heterocylic compounds.
In the title compound, the five-membered ring adopts an envelope conformation, with atom C8 forming the flap (Cremer & Pople, 1975). In the indane ring system atom C8 is 0.134 (1)Å out of the plane of the remaining essentially planar atoms. In the crystal structure, the molecules are linked into one-dimensional chains along the b axis (Fig. 2) by intermolecular O2—H1O2···O1i and weak C12—H12A···O3iii and C12—H12B···O36iii hydrogen bonds (Table 1).
