The title compound (AHTN-OH), C17H26O, was prepared in order to provide standard materials for the qualitative and quantitative analysis of environmental pollutants. The molecule possesses a chiral C atom, although the was performed on racemic material, expressed in the structure as disordered chiral sites. The consists of four AHTN-OH molecules containing an hydroxy group and forming a tetrameric cyclic motif built up by four strong hydrogen bonds between these hydroxy groups and additionally by two weak C—H⋯π interactions. Furthermore, these tetramers are linked via very weak C—H⋯π interactions, forming chains along the c axis.

For the solid state structure of AHTN, see De Ridder et al. (1990); for the partially oxidized derivatives AHTN-COOH, see: Kuhlich et al. (2010) and AHTN-CHO, see: De Ridder et al. (1994). The accumulation potential of AHTN in humans, wildlife and the environment is of concern (Luckenbach & Epel, 2005; Martin et al., 2007), especially as it has been shown to act as an endocrine disruptor (Luckenbach & Epel, 2005). For our efforts to provide standard materials for the qualitative and quantitative analysis of food contaminants, see: Siegel et al. (2009). For structure–fragrance relationships, see: Amoore (1970). Relationships of this kind increasingly take into account structural design elements such as molecular sites of hydrophilicity or intermolecular interactions such as hydrogen bonds, see: Beets (1957, 1978); Dravnieks & Laffort (1972). The title compound was obtained by the oxidation of the AHTNs acyl side chain to a carboxylic acid, followed by carboxyl reduction to the primary alcohol, see: Valdersnes et al. (2006).

A solution of 3,5,5,6,8,8-hexamethyl-5,6,7,8-tetrahydronaphthalene-2- carboxylic acid (AHTN-COOH, 913 mg, 3.5 mmol) (Kuhlich et al., 2010) in dry diethylether (100 ml) was added (1 h) at 50 °C to a stirred suspension of LiAlH4 (540 mg, 14.2 mmol) in diethylether (40 ml). After 0.5 h the cooled (0 °C) reaction mixture was carefully hydrolyzed with H2O (120 ml) and acidified with 6 M HCl solution (90 ml). The mixture was extracted with CH2Cl2 (90 ml), the organic phase dried over MgSO4, filtered and the solvent was evaporated under reduced pressure. Crystallization from ethyl acetate followed by
(SiO2, CHCl3/MeOH 3:1) gave the product as colorless solid [m.p. 111 °C]. Single crystals of (3,5,5,6,8,8-hexamethyl-5,6,7,8-tetrahydronaphthalen-2-yl)methanol suitable for X-ray diffraction were obtained by slow evaporation of an ethyl acetate solution (Valdersnes et al., 2006).The structure shows disorder, which could be resolved at positions C8/C8a, C25/C25a, C42/C42a and C59/C59a. The split positions were included to the model with fixed occupancy parameters of 0.5. Hydrogen atoms at the positions depicted with "a" were not included to the model. The expectable split positions of the adjacent atoms could not be refined.
The carbon bonded H atoms were placed in calculated positions (C-H:0.95-0.99Å) and refined according to the riding model with the 1.2 fold isotropic displacement parameter of their bonding partner. The H atoms of the OH groups were refined according to the rotating group routine (O-H: 0.85Å) and ended up in the expected positions for the O—H···O hydrogen bonds.

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. |

6-Acetyl-1,1,2,4,4,7-hexamethyltetraline (AHTN, TonalideR is a member of a group of synthetic fragrances designed to emulate the scent of natural musk. It is widely used in perfumes, cosmetics, detergents and air fresheners and hence is produced in several thousand tons per year worldwide. However, its accumulation potential in humans, wildlife and in the environment currently gives rise to concern, (Luckenbach & Epel, 2005; Martin et al., 2007) in particular in view of the fact that AHTN has been shown to act as an endocrine disruptor by inhibiting the cellular xenobiotic defense system (Luckenbach & Epel, 2005). A possible metabolite of the lipophilic AHTN is the title compound (3,5,5,6,8,8-hexamethyl-5,6,7,8-tetrahydronaphthalene-2-yl)methanol 1 (AHTN-OH), formally obtained by the oxidation of the AHTNs acyl side chain to a carboxylic acid followed by carboxyl reduction to the primary alcohol (Valdersnes et al., 2006). In our continuing effort to provide standard materials for the qualitative and quantitative analysis of food contaminants (Siegel et al., 2009) and environmental pollutants, we have elucidated the crystal structure of 1. These data will assist, for example, fragrance designers in establishing structure-fragrance relationships (Amoore, 1970; Beets, 1978). Relationships of this kind increasingly take into account structural design elements such as molecular sites of hydrophilicity or intermolecular interactions such as hydrogen bonds (Beets, 1957; Dravnieks & Laffort, 1972). The solid state structures of AHTN, (De Ridder et al., 1990) and of the partially oxidized derivatives AHTN-COOH (Kuhlich et al., 2010) and AHTN-CHO (De Ridder et al., 1994) have been reported.
AHTN-OH 1 crystallizes in an orthorhombic unit cell of the non-centrosymmetric space group P n 21 a. The asymmetric unit contains 4 formular units that are bonded via four strong hydrogen bonds, forming a four-membered cyclic arrangement (Table 1). No further intermolecular bonds, hydrogen bonds or other strong interactions between these tetrameric units can be observed. Since the starting material AHTN was used as a racemic mixture in the synthesis of 1, 1 is found to occur as a racemic mixture in the crystal. In the present case both enantiomers are represented by the split positions of the methylene groups at C8, C25, C42 and C59 (only one split position is shown in Fig. 1). Each split position determines the R or S configuration of the adjacent atoms C7, C24, C41 and C58, respectively. The present study does therefore not allow a correlation between the olfactoric qualities and the absolute configuration of the two enantiomers of 1. It is evident, however, that the vapor pressure (cf. the relatively high mp. of 1) and hence the fragrance intensity of 1 is significantly reduced compared to related compounds such as the parent AHTN, AHTN-CHO and AHTN-COOH, which are less engaged in hydrogen bonded networks in the solid state.
