Comment top

In previous work, we reported a compound of 2,4,6-triamino-1,3,5-triazin-1-ium with organic anion linked via weak interactions (Li et al., 2005). As continuing interest, here, we present the results of the crystal structure of another ion pair adduct containing monoprotonated melaminium, inorganic anion (hydrogen phosphate), and solvent water, (I, Fig. 1 & Table 1).

The aromatic rings both monoprotonated melaminium exhibit significant distortions from the ideal hexagonal form. Thus, the internal C—N—C angles at the protonated N atoms (C1—N3—C2 and C6 N8 C5) are significantly greater than the other two ring (i.e. C1—N2—C2, C1—N1—C3, C5—N7—C4, C6—N9—C4) angles, and the internal N2—C1—N1and N7—C4—N9 angle, i.e. containing only non-protonated N atoms is greater than either of the remaining N—C—N angles containing both protonated and non-protonated N atoms (Table 1). This feature of the structure is similar to our previous report (Li et al., 2005) and the other reported mono-protonated melaminium cations (Janczak & Perpétuo, 2001a,b,c, 2002, 2003, 2004; Perpétuo & Janczak, 2002; Zhang et al., 2004; Choi et al., 2004).

Between charged residues and the water molecules interact extensively by a combination of ionic, H-bonds (Table 2) as well as π-π interactions as shown in Fig 2. Neighboring melaminium residues are interconnected by double N—H···N H-bonds, leading to the formation of layers.

Experimental top

Hot solutions of melamine and meta-phosphoric acid in a 1:1 molar ratio were mixed and, after allowed the mixture to stand at room temperature for a few days, colourless blocks of (I) were desposited.

Refinement top

H atoms attached to N (except N3 and N8) and O1 atoms of (I) were placed in geometrically idealized positions with N—H = 0.86 Å O1—H = 0.82 Å and refined with Uiso=1.2Ueq [N] or Uiso=1.5Ueq [O1]. H atoms attached to O (water) N3 and N8 atom were located from the difference Fourier maps and refined their global Uiso=1.2Ueq. The N3—H, N8—H, and O—H distances are in the range 0.768 - 0.851 Å. The O2, O3, and, O4 atoms from hydrogen phosphate anion of crystallization in (I) were found to be disordered and were modelled over two sets of positions using restraints on the anisotropic displacement parameters of these O atoms. The major and minor disorder components had refined occupancies of O2A 0.77 (1), O3A 0.76 (1), O4A 0.76 (1) % and O2B 0.23 (1) O3B 0.24 (1)O4B 0.24 (1)%, respectively.

Special details top

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.
