In the cation of the title compound C9H14ON+·C3H2O3N3, the benzyl­amine C—N bond subtends a dihedral angle of 78.3 (2)° with the phenyl ring. The cyanurate anion is in the usual keto-form and shows an r.m.s. deviation from planarity of 0.010 Å. In the crystal, the cyanurate anions form N—H⋯O hydrogen-bonded zigzag ribbons along [001]. These ribbons are crosslinked by the organocations via O—H⋯N and N—H⋯O hydrogen bonds, forming bilayers parallel to (010) which are held together along [010] by slipped ππ inter­actions between pairs of cyanurate anions [shortest contact distances C⋯C = 3.479 (2), O⋯N = 3.400 (2); centroid–centroid distance= 4.5946 (9) Å] and between cyanurate and phenyl rings [centroid–centroid distance = 3.7924 (12) Å, ring–ring angle = 11.99 (10)°].

Cyanuric acid and trithiocyanuric acid are based on planar six-membered rings and are used as building blocks of supramolecular assemblies held together via a variety of intermolecular hydrogen bonds. In undissociated form they contain in the solid state three hydrogen donors (N—H) and three hydrogen acceptors (O, S). In this form cyanuric acid generates adducts with pyridine (Sivashankar, 2000), 4,4'-bipyridyl (Ranganathan et al., 2000) and melamine (Prior et al., 2013). And both, cyanuric and trithiocyanuric acid are found in mono- and di-anionic form in various organic salts (Krepps et al., 2001; Barszcz et al., 2006), particularly as ammonium salts such as tripropylammonium (Yang, 2010), 1-dimethylammonio-8-dimethylaminonaphthalene (Nichol & Clegg, 2006), and guanidinium (El-Gamel et al., 2008). Here we report the synthesis and crystal structure of the salt N-benzyl-2-hydroxyethanaminium cyanurate, [C9H14ON]+[C3H2O3N3]-.

The asymmetric unit of the title compound is formed by one molecule of the cyanurate anion and one molecule of the N-benzyl-2-hydroxyethanaminium cation (Fig. 1). The cyanurate anions are mutually linked via two pairs of centrosymmetric hydrogen bonds (N3—H3···O2i and its inverse, N5—H5···O4ii and its inverse) to form zig-zag ribbons along [001], a motif frequently encountered in cyanuric acid, cyanurate salts, and cyanurate metal complexes (Falvello et al., 1997; Sivashankar, 2000; Hou et al., 2011). Each N-benzyl-2-hydroxyethanaminium cation links two adjacent cyanurate zig-zag ribbons via the hydrogen bonds O1—H1···N1 and N2—H2A···O2iii two form a 2-dimensional infinite bilayer parallel to (010) (Fig. 2). This bilayer is reinforced by the intercationic hydrogen bond N2—H2B···O1iii and by an inclined π-π interaction between the cyanurate and the phenyl ring (CgCg = 3.7924 (12) Å, ring-ring angle = 11.99 (10)°). Adjacent bilayers are held together along [010] by slipped π-π interactions between centrosymmetric pairs of cyanurate anions (shortest contact distances C4···C4(1-x,-y,1-z) = 3.479 (2) Å, O1···N3(1-x,-y,1-z) = 3.400 (2) Å; CgCg = 4.5946 (9) Å). The incorporation of the N-benzyl-2-hydroxyethanaminium cation into the bilayer determines the conformation of the cation, which shows torsion angles of C10—C9—C15—N2 = 78.3 (2), C9—C15—N2—C8 = -168.71 (14), and C15—N2—C8—O1 = 59.3 (2)° for side chain atoms. The cyanurate ion is almost planar (r.m.s. and maximum deviations from planarity are 0.010 Å and 0.037 (15) Å (N5)).

Experimental top

A mixture of triethylamine (1.5 g, 14.8 mmol) and 2-(benzylamino)ethanol (2 g, 13.5 mmol) was added slowly to methanolic solution of cyanuric chloride (0.83 g, 4.4 mmol) in an ice bath under stirring. The resulting solution was set to reflux for three days, and then allowed to cool down until the formation of a crystalline material was observed. The colourless crystalline material was filtered and washed with acetone and cold methanol.

Refinement top

C-bonded H atoms were included in calculated position (C—H = 0.93 Å for aromatic H, and C—H = 0.97 Å for methylene H), and refined using a riding model with Uiso(H) = 1.2 × Ueq of the carrier atoms. H atoms on N and O were located in a Fourier map and refined isotropically with Uiso(H) = 1.2 × Ueq(N) or 1.5 × Ueq(O).

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.
