The five-membed ring of the title compound, C11H13NO, that is fused with the aromatic ring is approximately planar (r.m.s. deviation = 0.037 Å) despite the presence of the sp3-hybridized ethylene linkage. The hydroxy group of the N-bound hydroxyethyl chain serves as hydrogen-bond donor to the azomethine N atom of an adjacent molecule, generating a hydrogen-bonded C2-symmetric dimer.

A mixture of 2-amino ethanol (0.6 g, 10 mmol) and 1-indanone (1.3 g, 10 mmol) in dry benzene (50 ml) was refluxed in a Dean-Stark apparatus until no more water was collected (in about 2 h). The solvent was then removed under reduced pressure and the residue treated with methanol. The solid which separated out was recystalized from ethanol to give colorless, 418–419 K.
Carbon bound H-atoms were placed in calculated positions [C–H 0.95 to 0.99 Å, Uiso(H) 1.2Ueq(C)] and were included in the
in the riding model approximation.The hydroxy H-atom was located in a difference Fouier map and was freely refined.

A enormously large number of Schiff base derivatives of aldehydes and ketones have been synthesized; however, 1-indanone represents an anomaly as only few have been reported. In the 2-aminoethanol derivative (Scheme I), the five-membed cyclohexene ring is planar despite the presence of sp3-hybridized ethylene linkage molecule (Fig. 1). The hydroxy group of the N-bound hydroxyethyl chain serves as hydrogen-bond donor to the azomethine N atom of an adjacent molecule to generate a hydrogen-bonded dinuclear molecule (Table 1). However, there is no significant π interaction of the rings as the distances between them exceed 3.5 Å (Fig. 2). The compound has not been reported in the chemical literature; on the other hand, the corresponding reduced amine is a reagent for the synthesis of pharmaceuticals (Stange et al., 1957).
