In the 12H14N3+·C2H2ClO2−, the chloroacetate anion is linked to the N-(4,6-dimethylpyrimidin-2-yl)aniline cation by N—H⋯O hydrogen bonding. Within the cation, the pyrimidine ring is twisted with respect to the phenyl ring by a dihedral angle of 7.59 (4)°.

The title compound was prepared by the reaction of N-(4,6-dimethylpyrimidin-2-yl)aniline (0.01 mol) and chloroacetic acid (0.01 mol) in anhydrous alcohol at room temperature for 1 h. Single crystals of suitable for X-ray measurements were obtained by by slow evaporation of anhydrous alcohol at room temperature.
The H atoms attached to N2 was located in a difference Fourier map and refined isotropically. Other H atoms were placed in calculated positions, with C—H = 0.93–0.98 Å, N—H = 0.86 Å, and included in final cycles of
using a riding model, with Uiso(H) = 1.2Ueq(C,N) or 1.5Ueq(C) for methyl H atoms.The 2-anilino-4,6-dimethylpyrimidine has a good and wide fungicidal activity (Xue et al., 2000; Li et al., 1996). The pyriminethanil could be combined with certain acids to form pyrimethanil salts that have a reduced vapor pressure that increased the persistence of the compounds on the crop to be protected from fungal attack, and increased activity (Stock et al., 1997).
The crystal of the title compound consists of 2-phenylamino-4,6-dimethylpyrimidinium cations and chloroacetate anions (Fig. 1). All bond lengths and angles are normal. The atoms of the pyrimidine ring are coplanar, the largest deviation from the mean plane being 0.005 (2)Å (N3). The dihedral angle between the pyrimidine and phenyl rings is 7.59 (4)°. The cation links with the anion via N—H···O hydrogen bonding (Table 1, Fig. 2).

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. |
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. |

The 2-anilino-4,6-dimethylpyrimidine has a good and wide fungicidal activity (Xue et al., 2000; Li et al., 1996). The pyriminethanil could be combined with certain acids to form pyrimethanil salts that have a reduced vapor pressure that increased the persistence of the compounds on the crop to be protected from fungal attack, and increased activity (Stock et al., 1997).
The crystal of the title compound consists of 2-phenylamino-4,6-dimethylpyrimidinium cations and chloroacetate anions (Fig. 1). All bond lengths and angles are normal. The atoms of the pyrimidine ring are coplanar, the largest deviation from the mean plane being 0.005 (2)Å (N3). The dihedral angle between the pyrimidine and phenyl rings is 7.59 (4)°. The cation links with the anion via N—H···O hydrogen bonding (Table 1, Fig. 2).
