4-Amino-3,5-bis(2-pyridyl)-4H-1,2,4-triazole-benzene-1,2,3-tricarboxylic acid-water (1/1/2)

Abstract top

Cocrystallization of 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole (2-bpt) with hemimellitic acid (benzene-1,2,3-tricarboxylic acid) dihydrate (H3HMA·2H2O) produces the supramolecular title compound, C12H10N6·C9H6O6·2H2O. Intermolecular N-H...N hydrogen bonds are observed between the terminal pyridyl and amino groups of the 2-bpt molecule and the dihedral angles between the central ring and the pendant pyridine rings are 3.4 (7) and 13.8 (7)°. In the structure, homosynthons of graph set R22(8) are observed to form centrosymmetric H3HMA dimers, which are extended into a two-dimensional supramolecular layer via intermolecular O-H...N and C-H...O hydrogen bonds and [pi]-[pi] stacking interactions [centroid-centroid distance = 3.541 (3) Å]. In addition, interlayer uncoordinated water molecules connect the layers through O-H...O hydrogen bonds, generating a three-dimensional network.

Comment top

Carboxylic acid is one of the most commonly used functional groups in designing specific organic solids (Kuduva et al., 1999; Das et al., 2006). Compared with the well studied trimesic acid (benzene-1,3,5-tricarboxylic acid, H3TMA; Biradha et al., 1998; Paz et al., 2003), its isomer hemimellitic acid (benzene-1,2,3-tricarboxylic acid, H3HMA) has received little attention, with only few co-crystal structures reported to date (Dale et al., 2004; Du et al., 2005). As regards the angular dipyridyl derivative 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole (2-bpt), it can possibly provide multiple supramolecular interaction sites for molecular recognition, but organic crystals in relation to this component has rarely been studied up to now (Mernari et al., 1998; Ramos Silva et al., 2008). Herein the crystal structure of the title crystalline solid, 2-bpt.H3HMA.2H2O, is reported, which displays a 3-D supramolecular architecture and represents the new organic crystal for 2-bpt molecule.

The asymmetric unit of the title compound (Fig. 1) contains one 2-bpt, one H3HMA acid and two lattice water molecules. The dihedral angle between the 2-bpt and H3HMA rings is 5.4 (4)°. The two pyridyl groups of 2-bpt deviate by 10.7 (7)° from coplanarity and form dihedral angels of 3.4 (7) and 13.8 (7)°, respectively, with the central triazolyl ring. In the H3HMA molecule, the O3/C4/O4 carboxyl group is nearly perpendicular to the benzene plane (dihedral angle 81.4 (7)°), while the corresponding angles for the O1/C1/O2 and O5/C6/O6 groups are 7.8 (1) and 22.1 (8)°, respectively. In the 2-bpt molecule, N5—H5A···N6 and N5—H5B···N1 intramolecular hydrogen interactions are observed, as expected, between the terminal pyridyl and amino groups (Table 1). The O5—C6—O6 carboxyl groups of centrosymmetrically related H3HMA molecules form strong intermolecular hydrogen bonds, affording a dimeric unit with homosynthon of graph set R22(8) (Table 1). Furthermore, the dimers connect adjacent 2-bpt molecules via the nearly perpendicular carboxyl groups (Table 1), generating a 1-D supramolecular array along the [010] direction (Fig. 2). In addition, intrachain C20—H20···O6 contacts (Table 1) and π–π stacking interactions (centroid-centroid distance = 3.541 (3) Å) extend the chains into a 2-D layer. The lattice water molecules occupy the interspaces of adjacent layers. The molecule including the O8 oxygen atom forms interlayer O8—H8A···N2, O8—H8B···O2 and C14—H14···O8 interactions, within which a R22(7) synthon can be observed (Table 1); the water molecule including the O7 oxygen atom hydrogen-bonds adjacent layers and water molecules to finally afford a 3-D supramolecular structure (Table 1, Fig. 3). Examination of the interlayer solvent volume by PLATON (Spek, 2009) reveals a value of 81.0 Å3 (7.5% of the unit cell volume).

A mixture of 2-bpt (Bentiss et al., 1999) (23.8 mg, 0.1 mmol), H3HMA.2H2O (24.6 mg, 0.1 mmol) and water (10 ml) was sealed in a Teflon-lined stainless steel vessel (20 ml), which was heated at 413 K for three days and then cooled to room temperature. Colourless block single crystals of the title compound were obtained in 52% yield (25.0 mg, based on 2-bpt). Anal. Calcd for C21H20N6O8: C, 52.07; H, 4.16, N, 17.35.

Refinement top

The water and amine H atoms were located in a difference Fourier map and refined with the O—H and N—H bond lengths constrained to 0.85 and 0.90 Å, respectively, and with Uiso(H) = 1.5Ueq(O) and 1.2Ueq(N). All other H atoms were placed at calculated positions and refined as riding, with C—H = 0.93 Å, O—H = 0.82 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
