In the crystal of the title co-crystalline adduct, C8H16N4·C8H9ClO, (I), prepared by solid-state reaction, the molecules are linked by intermolecular O—H⋯N hydrogen bonds, forming a D motif. The azaadamantane structure in (I) is slightly distorted, with N—CH2—CH2—N torsion angles of 10.4 (3) and −9.0 (3)°. These values differ slightly from the corresponding torsion angles in the free aminal cage (0.0°) and in related co-crystalline adducts, which are not far from a planar geometry and consistent with a D2d molecular symmetry in the tetraazatricyclo structure. The structures also differ in that there is a slight elongation of the N—C bond lengths about the N atom that accepts the hydrogen bond in (I) compared with the other N—C bond lengths. In the crystal, the two molecules are not only linked by a classical O—H⋯N hydrogen bond but are further connected by weak C—H⋯π interactions, forming a two-dimensional supramolecular network parallel to the bc plane.

1. Chemical context
In our continuing investigations on the reactivity of cyclic 3,8]dodecane (TATD) shows an interesting reactivity with 4-chloro-3,5-dimethylphenol under different conditions. Reaction between TATD with 4-chloro-3,5-dimethylphenol in solution yields symmetrical bis-benzoxazines (Rivera et al., 2005), but under heating in an oil bath (Rivera & Quevedo, 2013) or microwave-assisted solvent-free conditions, symmetrical N,N'-disubstituted imidazolidines (Rivera, Nerio & Bolte, 2015) are obtained. Therefore, we became interested in exploring the reactivity of TATD with under solvent-free conditions at room temperature. In the course of our investigations, we obtained the molecular salt 8,10,12-triaza-1-azoniatetracyclo[8.3.1.18,12.02,7]pentadecane 4-nitrophenolate 4-nitrophenol by grinding (2R,7R)-1,8,10,12-tetraazatetracyclo[8.3.1.18,12.02,7]pentadecane with 4-nitrophenol (Rivera, Uribe, Ríos-Motta et al., 2015) and the 1:2 adduct 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD)-4-bromophenol (Rivera, Uribe, Rojas et al., 2015) by grinding at room temperature.
of the adamantane type with we have found that 1,3,6,8-tetraazatricyclo[4.4.1.1Herein, we describe the synthesis of the title co-crystalline adduct 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD)–4-chloro-3,5-dimethylphenol under solvent-free conditions by simply grinding together the components at room temperature.
2. Structural commentary
The , has confirmed the presence of a 1:1 co-crystalline adduct. A view of this adduct is shown in Fig. 1. The of the title compound contains a 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD) and a 4-chloro-3,5-dimethylphenol molecule linked via an O—H⋯N hydrogen bond, forming a D motif (Bernstein et al., 1995). As in the 1:2 adduct with 4-bromophenol (Rivera, Uribe, Rojas et al., 2015) and the 1:1 adduct with hydroquinone (Rivera et al., 2007), the intermolecular O—H⋯N hydrogen bond in (I) also leads to a stable supramolecular structure, but comparison of the title compound with the above-mentioned related structures shows that the three adducts differ in the O⋯N hydrogen-bond distances [2.752 (2) Å in (I), 2.705 (5) Å in the 1:2 adduct and 2.767 (2) Å in the co-crystalline adduct with hydroquinone], which is in agreement with the differences in the pKa values between the species involved in the hydrogen bond (Majerz et al., 1997): 4-chloro-3,5-dimethylphenol (pKa = 9.76); p-bromophenol (pKa = 9.37) and hydroquinone (pKa = 9.85) (Lide, 2003).
of the title compound, (I)To a first approximation, the geometric parameters of the title molecule agree well with those reported for similar structures (Rivera et al., 2007; Rivera, Uribe, Rojas et al., 2015) and are within normal ranges (Allen et al., 1987), but compared to the free aminal cage structure (Rivera et al., 2014) which belongs to the D2d two small differences are noted. The azaadamantane structure in (I) is slightly distorted, with N—CH2—CH2—N torsion angles of 10.4 (3)° (N1—C1—C2—N2) and −9.0 (3)° (N3—C7—C8—N4). These values differ slightly from the values of the corresponding torsion angles in the free aminal cage (0.0°; Rivera et al., 2014), and the related co-crystalline adducts [2.4 (7)° (Rivera, Uribe, Rojas et al., 2015) and −0.62° (Rivera et al., 2007)] which shows that each N—C—C—N group is not far from a planar geometry and consistent with a D2d molecular symmetry in the tetraazatricyclo structure. Furthermore, the structures also differ in the slight elongation of the N1—C bond lengths of the nitrogen atom that accepts the hydrogen bond, [1.470 (2) and 1.480 (2) Å], compared to the the other N—C bond lengths (Table 1).

3. Supramolecular features
The two different molecules in (I) are connected by a classical O—H⋯N hydrogen bond. The crystal packing is further stabilized by weak intermolecular C—H⋯π interactions, linking the molecules into two-dimensional sheets in the bc plane (Table 2 and Fig. 2). Furthermore, there are short N⋯Cl contacts [N4⋯Cl1i 3.1680 (15) Å; symmetry operator: (i) x, −y, z − ] linking the molecules into zigzag chains running along the c-axis direction (Fig. 3).
4. Database survey
The geometric parameters of 4-chloro-3,5-dimethylphenol in (I) (Table 1) agree well with those of found in the containing only this molecule (Cox, 1995), which crystallized with two molecules in the [C—O = 1.387 (3) and 1.378 (3) Å; C—Cl = 1.752 (2) and 1.749 (2) Å; C—Cmethyl = 1.502 (3), 1.500 (3), 1.514 (3) and 1.505 (3) Å]. For 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane, two comparable structures were retrieved from the CSD (Groom & Allen, 2014). A least-squares fit of the structure that contains only 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (Rivera et al., 2014) gives an r.m.s. deviation of 0.048 Å with 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane of (I) and a least-squares fit of 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane co-crystallized with hydroquinone (Rivera et al., 2007) gives an r.m.s. deviation of 0.051 Å with 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane of (I). Thus, it can be concluded that the conformational freedom of 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane is rather limited.
5. Synthesis and crystallization
A mixture of 1,3,6,8-tetraazatricyclo[4.4.1.3,8]dodecane (TATD) (168 mg, 1 mmol) and 4-chloro-3,5-dimethylphenol (157 mg, 1 mmol) was ground using a mortar and pestle, at room temperature for 15 min., as required to complete the reaction (TLC). The mixture was then dissolved in methanol. Crystals suitable for X-ray diffraction were obtained from a methanol solution upon slow evaporation of the solvent at room temperature.
6. Refinement
Crystal data, data collection and structure . All H atoms were located in difference electron-density maps. The hydroxyl H atom was refined freely, while C-bound H atoms were fixed geometrically (C—H = 0.95, 0.98 or 0.99 Å) and refined using a riding model, with Uiso(H) values set at 1.2Ueq (1.5 for methyl groups) of the parent atom. The methyl groups were allowed to rotate but not to tip.

Herein, we describe the synthesis of the title co-crystalline adduct 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD)-4-chloro-3,5-dimethylphenol under solvent-free conditions by simply grinding together the components at room temperature.The
of the title compound, (I), has confirmed the presence of a 1:1 co-crystalline adduct. A view of this adduct is shown in Fig. 1. The of the title compound contains a 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD) and a 4-chloro-3,5-dimethylphenol molecule linked via an O—H···N hydrogen bond, forming a D motif (Bernstein et al., 1995). As in the 1:2 adduct with 4-bromophenol (Rivera, Uribe, Rojas et al., 2015) and the 1:1 adduct with hydroquinone (Rivera et al., 2007), the intermolecular O—H···N hydrogen bond in (I) also leads to a stable supramolecular structure, but comparison of the title compound with the other related structures shows that the three adducts differ in the O···N hydrogen-bond distances [2.752 (2) Å in (I), 2.705 (5) Å in the 1:2 adduct and 2.767 (2) Å in the co-crystalline adduct with hydroquinone], which is in agreement with the differences in the pKa values between the species involved in the hydrogen bond (Majerz et al., 1997): 4-chloro-3,5-dimethylphenol (pKa = 9.76); p-bromophenol (pKa = 9.37) and hydroquinone (pKa = 9.85) (Lide, 2003).To a first approximation, the geometric parameters of the title molecule agree well with those reported for similar structures (Rivera et al., 2007; Rivera, Uribe, Rojas et al., 2015) and are within normal ranges (Allen et al., 1987), but compared to the free aminal cage structure (Rivera et al., 2014) which belongs to the D2d
two small differences are noted. The azaadamantane structure in (I) is slightly distorted, with N—CH2—CH2—N torsion angles of 10.4 (3)° (N1—C1—C2—N2) and -9.0 (3)° (N3—C7—C8—N4). These values differ slightly from the values of the corresponding torsion angles in the free aminal cage (0.0°; Rivera et al., 2014), and the related co-crystalline adducts [2.4 (7)° (Rivera, Uribe, Rojas et al., 2015) and -0.62° (Rivera et al., 2007)] which shows that each N—C—C—N group is not far from a planar geometry and consistent with a D2d molecular symmetry in the tetraazatricyclo structure. Furthermore, the structures also differ in the slight elongation of the N1—C bond lengths of the nitrogen atom that accepts the hydrogen bond, [1.470 (2) and 1.480 (2) Å], compared to the the other N—C bond lengths (Table 1).The two different molecules in (I) are connected by a classical O—H···N hydrogen bond. The crystal packing is further stabilized by weak intermolecular C—H···π interactions, linking the molecules into two-dimensional sheets in the bc plane (Table 2 and Fig. 2). Furthermore, there are short N···Cl contacts [N4···Cl1i 3.1680 (15) Å symmetry operator: (i) x, -y, z - 1/2] linking the molecules into zigzag chains running along the c-axis direction (Fig. 3).

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. |
