The title compound was obtained as a gift sample from R. L. Fine Chem, Bangalore, India. X-ray quality crystals were obtained by slow evaporation from toluene solution at room temperature.
Carbon-bound H atoms were placed in calculated positions (C—H 0.95 Å for aromatic carbon atoms, C—H 0.99 Å for methylene groups) and were included in the
in the riding model approximation, with U(H) set to 1.2Ueq(C). The H atoms of the methyl groups were allowed to rotate with a fixed angle around the C—C bond to best fit the experimental electron density (HFIX 137 in the SHELX program suite (Sheldrick, 2008), with U(H) set to 1.5Ueq(C). Both oxygen-bound H atoms were placed in calculated positions (O—H 0.94 Å) and were included in the in the riding model approximation, with U(H) set to 1.5Ueq(O).2-(2-Benzylphenyl)propan-2-ol is used in synthetic organic chemistry for the preparation of many organic compounds including anthrone. Benzhydrols are widely used as intermediates for the synthesis of pharmaceuticals (Ohkuma et al., 2000). The crystal structures of 2-(5-bromo-2-methylphenyl)propan-2-ol (Zeng & Liu, 2010), 10,10-dimethylanthrone (Fun et al., 2010), (2-methylphenyl)(phenyl)methanol (Siddaraju et al., 2010), 9,9-dimethyl-9,10-dihydroanthracene (Siddaraju et al., 2011) and a N,N-dimethylamino-substituted analogue of the title compound (Gu et al., 2009) have been reported earlier. In view of the importance of the title compound, its
was determined.The
contains two complete molecules. The least-squares planes defined by the carbon atoms of the different phenyl moieties in each molecule enclose angles of 82.58 (10)° and 88.66 (13)°, respectively (Fig. 1).In the crystal, cooperative hydrogen bonds connect the molecules to discrete tetramers. The plane defined by the atoms of the participating hydroxyl groups is perpendicular to the crystallographic b axis. In terms of graph-set analysis (Etter et al., 1990; Bernstein et al., 1995), the descriptor for the hydrogen bonds is DD on the unitary level and R44(8) on the binary level. The shortest intercentroid distance between two aromatic systems was measured at 4.9147 (14) Å and is observed between the two different phenyl rings of one of the molecules present in the
and its symmetry-generated equivalent (Fig. 2).The packing of the title compound in the crystal is shown in Figure 3.

2-(2-Benzylphenyl)propan-2-ol is used in synthetic organic chemistry for the preparation of many organic compounds including anthrone. Benzhydrols are widely used as intermediates for the synthesis of pharmaceuticals (Ohkuma et al., 2000). The crystal structures of 2-(5-bromo-2-methylphenyl)propan-2-ol (Zeng & Liu, 2010), 10,10-dimethylanthrone (Fun et al., 2010), (2-methylphenyl)(phenyl)methanol (Siddaraju et al., 2010), 9,9-dimethyl-9,10-dihydroanthracene (Siddaraju et al., 2011) and a N,N-dimethylamino-substituted analogue of the title compound (Gu et al., 2009) have been reported earlier. In view of the importance of the title compound, its crystal structure was determined.
The asymmetric unit contains two complete molecules. The least-squares planes defined by the carbon atoms of the different phenyl moieties in each molecule enclose angles of 82.58 (10)° and 88.66 (13)°, respectively (Fig. 1).
In the crystal, cooperative hydrogen bonds connect the molecules to discrete tetramers. The plane defined by the atoms of the participating hydroxyl groups is perpendicular to the crystallographic b axis. In terms of graph-set analysis (Etter et al., 1990; Bernstein et al., 1995), the descriptor for the hydrogen bonds is DD on the unitary level and R44(8) on the binary level. The shortest intercentroid distance between two aromatic systems was measured at 4.9147 (14) Å and is observed between the two different phenyl rings of one of the molecules present in the asymmetric unit and its symmetry-generated equivalent (Fig. 2).
The packing of the title compound in the crystal is shown in Figure 3.
