The racemic title compound, C23H28O2, crystallizes in the C2/c as a layered structure in which a centrosymmetric three hydrogen bond sequence links four molecules. Both hydroxy groups are involved in this arrangement, but they differ in that one participates in two hydrogen bonds while the other takes part in only one. Between layers, the aromatic rings take part in edge-face interactions [shortest C—H⋯C distances 3.04, 3.10 and 3.12 Å and angle between normal to planes 86.7(2)°], forming a centrosymmetric dimer. The lattice is further stabilized by C—H⋯π interactions involving both methyl (shortest C⋯C 3.82 and 3.97 Å) and methylene (shortest C⋯C 3.60 Å) groups.
Related literature
Phenylation of endo-4, endo-8-dimethylbicyclo[3.3.1]nonane-2,6- dione (Kim et al., 2002) occurs selectively on the exo-faces of the V-shaped molecule to yield the title compound. The related 2,6-dimethyl- substituted compound (Nguyen et al., 2001b) crystallizes with a hydrogen-bonded ladder structure (Nguyen et al., 2001a) that is very different to the pattern reported here.

A solution of racemic endo-4,endo-8-dimethylbicyclo[3.3.1]nonane-2,6-dione (Kim et al., 2002) (0.79 g, 4.4 mmol) in dry tetrahydrofuran (30 ml) was added dropwise to a stirred solution of excess phenylmagnesium bromide in dry diethyl ether (10 ml) at -10°C. After 12 h at rt, the reaction was subjected to a standard Grignard reaction work-up to yield the title compound (0.67 g, 47%), m.p. 438-440 K (from acetonitrile). Found: C 82.15, H 8.34; C23H28O2 requires C 82.10, H 8.39%. 13C NMR (75.5 MHz, CDCl3) δ: 22.0 (CH3), 32.5 (CH2), 36.2 (CH), 42.4 (CH), 42.6 (CH2), 78.4 (C), 125.5 (CH), 127.0 (CH), 128.2 (CH), 148.3 (C). 1H NMR (300 MHz, CDCl3) δ: 1.18 (t, J=3.0 Hz, 2H), 1.46 (d, J=6.4 Hz, 6H), 1.57 (bs, 2H, exchanged with D2O), 2.18–2.39 (m, 6H), 2.44–2.47 (m, 2H), 7.22–7.27 (m, 2H), 7.31–7.36 (m, 4H), 7.52–7.55 (m, 4H). X-ray quality crystals were obtained from tetrahydrofuran solution.
The hydrogen atoms on the hydroxy groups are disordered over two sites of equal occupancy. This is a requirement of the centrosymmetric hydrogen bonding arrangement found in the lattice. The hydroxy hydrogen atoms were located on a difference map, and were then fixed at a position along the OH vector with O—H = 1.0 Å. Hydrogen atoms attached to C were included at calculated positions (C—H = 1.0 Å). All hydrogen atoms were refined with isotropic thermal parameters equivalent to those of the atom to which they were bonded.

Molecules (Fig. 1) are linked by a centrosymmetric triplet of hydrogen bonds utilizing one hydroxy group from each of four molecules (Table 1). The other hydroxy group of each of these molecules participates in an identical hydogen bonding unit, leading to a layer structure in the bc plane (Fig. 2). The hydrogen bonding in this compound is somewhat unusual in that hydroxy group, O1, participates in two hydrogen bonds, whereas O2 only participates in one. The majority of the alicyclic diols studied by us (Kim et al., 2002) have one donor and one acceptor hydrogen bond for each hydroxy group.
The pendant phenyl rings do not participate in the common aromatic offset face-to-face interaction in the crystal structure. Instead, one phenyl ring (C10→C15) is the acceptor of two Cmethyl—H···π interactions, one to each surface of the ring (C16—H···π, C23—H···π with shortest H···C distances of 3.97 and 3.82 Å, respectively). The second phenyl ring (C17→C22) takes part in a Cmethylene—H···π interaction on one surface (C3—H···π with a shortest H···C distance of 3.60 Å). Its second surface is the acceptor of an edge-to-face interaction utilizing the edge of the C10→C15 ring and creating a centrosymmetric dimer between layers (Fig. 3).
