A mixture of (1S,2R)-(-)-amino-2-indanol (0.149 g,1 mmol) and 2-thiophene carboxaldehyde (0.112 g,1 mmol) was stirred in ethanol for 24 h. The residue, obtained by removing the solvent under vacuum, was recrystallized in dichloromethane. The desired product was isolated as white crystals after the solution remained at -20 °C in a refrigerator for a few days (yield 80%, 0.195 g).
The H-atoms were included in calculated positions and treated as riding atoms: Uiso(H) = 1.2Ueq(parent C-atom),Uiso(H) = 1.5Ueq(parent O-atom).
Multidentate ligands having thiophene groups have received a great attention due to their unique binding abilities (Jeong et al., 2011; Dong et al., 2006; Lee et al., 1999). Aminoindaol type ligands have been also extensively used as chiral chelating ligands (Lee et al., 2007; Flores-Lopes et al., 2000). As a part of our ongoing project on the synthesis of new ONS-type tridentate monoanionic chelating ligands, the title compound was synthesized by the reaction of 2-thiophene carboxaldehyde with (1S,2R)-(-)-cis-amino-2-indanol and its
is reported herein.In the title compound (Fig. 1), the C7 carbon atom is displaced by 0.450 (2) Å from the mean plane defined by the C6/C8–C14 atoms of the indane ring system. The dihedral angle formed by the mean planes through the indane ring system and the thiophene is 85.04 (11) °. The
is stabilized by an intramolecular O—H···N hydrogen bond (Table 1). The is assigned on the basis of the which is consistent with the known configuration of the indanol employed in the synthesis.For metal complexes containing aminoindanol ligands, see: Lee et al. (2007); Flores-Lopes et al. (2000). For metal comlexes with thiophene-type ligands, see: Jeong et al. (2011); Dong et al. (20061999); Lee et al. (1999).

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. |

Multidentate ligands having thiophene groups have received a great attention due to their unique binding abilities (Jeong et al., 2011; Dong et al., 2006; Lee et al., 1999). Aminoindaol type ligands have been also extensively used as chiral chelating ligands (Lee et al., 2007; Flores-Lopes et al., 2000). As a part of our ongoing project on the synthesis of new ONS-type tridentate monoanionic chelating ligands, the title compound was synthesized by the reaction of 2-thiophene carboxaldehyde with (1S,2R)-(-)-cis-amino-2-indanol and its crystal structure is reported herein.
In the title compound (Fig. 1), the C7 carbon atom is displaced by 0.450 (2) Å from the mean plane defined by the C6/C8–C14 atoms of the indane ring system. The dihedral angle formed by the mean planes through the indane ring system and the thiophene is 85.04 (11) °. The molecular conformation is stabilized by an intramolecular O—H···N hydrogen bond (Table 1). The absolute configuration is assigned on the basis of the Flack parameter, which is consistent with the known configuration of the indanol employed in the synthesis.
