In the 4H10NO+·C6HCl2O4−·CH4O, the components are held together by bifurcated O—H⋯(O,O), O—H⋯(O,Cl) and N—H⋯(O,O) hydrogen bonds into a centrosymmetric 2+2+2 aggregate. The aggregates are further connected by another bifurcated N—H⋯(O, O) hydrogen bond, forming a double-tape structure along the b axis. A weak C—H⋯O interaction is observed between the tapes.

Single crystals were obtained by slow evaporation from a methanol solution (50 ml) of chloranilic acid (0.102 g) and morpholine (0.044 g) at room temperature.
C-bound H atoms were positioned geometrically (C—H = 0.98 or 0.99 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). The O– and N-bound H atoms were found in a difference Fourier map and refined freely. The refined distances are O—H = 0.82 (2) and 0.742 (19) Å, and N—H = 0.852 (19) and 0.878 (18) Å.
The title compound was accidentally obtained in the preparation of morpholinium hydrogen chloranilate (Ishida & Kashino, 1999), C4H10NO+.C6HCl2O4-, which is an interesting model compound for investigating proton transfer in the hydrogen bond systems (Ikeda et al., 2005; Asaji, Hoshino et al., 2010; Asaji, Seliger et al., 2010).
In the title compound, the three components (Fig. 1) are held together by bifurcated O—H···(O, O), O—H···(O, Cl) and N—H···(O, O) hydrogen bonds [O2—H2···(O3, O6), O6—H6···(O3i, Cl2i) and N1—H1A···(O3, O3i); symmetry code in Table 1] into a centrosymmetric 2 + 2+2 aggregate (Fig. 2). The aggregates are connected by another N—H···(O, O) hydrogen bond between the cation and the anion [N1—H1B···(O1ii, O4ii), symmetry code in Table 1], forming a double-tape structure along the b axis (Fig. 3). The tapes are further linked a weak C—H···O interaction, forming a three-dimensional network.

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 title compound was accidentally obtained in the preparation of morpholinium hydrogen chloranilate (Ishida & Kashino, 1999), C4H10NO+.C6HCl2O4-, which is an interesting model compound for investigating proton transfer in the hydrogen bond systems (Ikeda et al., 2005; Asaji, Hoshino et al., 2010; Asaji, Seliger et al., 2010).
In the title compound, the three components (Fig. 1) are held together by bifurcated O—H···(O, O), O—H···(O, Cl) and N—H···(O, O) hydrogen bonds [O2—H2···(O3, O6), O6—H6···(O3i, Cl2i) and N1—H1A···(O3, O3i); symmetry code in Table 1] into a centrosymmetric 2 + 2+2 aggregate (Fig. 2). The aggregates are connected by another N—H···(O, O) hydrogen bond between the cation and the anion [N1—H1B···(O1ii, O4ii), symmetry code in Table 1], forming a double-tape structure along the b axis (Fig. 3). The tapes are further linked a weak C—H···O interaction, forming a three-dimensional network.
