(Received 4 November 2010; accepted 8 November 2010; online 17 November 2010)

In the crystal of the title compound, C8H12N5+·C4H5O4−·CH3OH, the hydrogen succinate anions form infinite [010] chains via short, almost symmetrical, O⋯H⋯O hydrogen bonds. The 2-phenyl­biguanidium cations inter­connect these chains into layers lying parallel to the bc plane by way of N—H⋯O links. These planes only weakly inter­act in the direction of the a axis via C—H⋯π contacts between offset phenyl rings, leaving as much as 17% of the unit-cell volume accessible for the solvent. However, the methanol solvent mol­ecules could not be resolved due to extensive disorder and their assumed presence was removed from the overall scattering by the PLATON SQUEEZE procedure.

Comment top

Biguanides are strong σ- and π-donating ligands, which form stable complexes (Marchi et al., 1999; Ray, 1961) with transition metal ions in high or unusual oxidation states. Biguanide complexes of boron have also been investigated as potential compounds for wood conservation (Anderson et al., 1995).

Another application of biguanides lies in the field of medicine (Sirtori & Pasik, 1994; Clement & Girreser, 1999). N-dimethylbiguanide and N-phenylethylbiguanide are used for the treatment of diabetes mellitus (Thompson et al., 1999; Ross et al., 2004; Woo et al., 1999), therapeutic treatment of pain, anxiety, memory disorders (Morain et al., 1994). Biguanide and its derivatives are also produced as antimalarial drugs (Watkins et al., 1987) and drugs with hypoglycaemic activity (Marchi et al., 1999; Sirtori & Pasik, 1994; Shapiro et al., 1959a,b).

We have prepared and discussed N-phenylbiguanide compounds within our project of searching for new materials with nonlinear optical properties (Matulková et al., 2010; Matulková et al., 2008), where N-phenylbiguanidinium(1+) cations can act as an polarizable compound with delocalized π-electron. The molecular conformation of title compound, (I), is illustrated in Fig. 1.

The hydrogen-bonding geometries in title compound are listed in list of hydrogen bonds and illustrated in Fig. 2. A number of intra- and intermolecular hydrogen bonds stabilize the molecular conformation. The crystal structure is built up chains (along the axis b) of hydrogen succinate anions with the shared hydrogen atoms with occupancy 0.5 (hydrogen bond O2 - H2···O4 with D···A distances of 2.451 (2) Å). These chains are interconnected by 2-phenylbiguanidium cations to form a three-dimensional network. A residue electron density of disordered molecules of methanol was found on the diferential Fourier map and the crystal structure was solved by a SQUEEZE method (van der Sluis & Spek, 1990). Free cavities of maximum on the Fourier map are indicated by blue spheres and are located in the 30% of crystal structure. The cavities can be filled by spheres of two types with the radii 2.247 Å and 2.076 Å (see Fig. 3). The unit cell contains two spheres of each size.

Experimental top

The crystals of the title compound, were obtained from solution of 0.2 g of N-phenylbiguanide (98%, Aldrich) and 0.14 g of succinic acid (p.a., Lachema) in 10 ml of water. The solution was left to crystallize at room temperature for several weeks. The colourless crystals obtained were filtered off, washed with methanol and dried in vacuum desiccator over KOH. The melting point ranges 410–412 K.

The infrared spectra were recorded at room temperature using DRIFTS and the nujol or fluorolube mull techniques on a Nicolet Magna 760 FTIR spectrometer with 2 cm-1 resolution (4 cm-1 resolution in FAR IR region) and Happ-Genzel apodization in the 85–4000 cm-1 region.

Refinement top

H atoms attached to C and N atoms were calculated in geometrically idealized positions, with Csp3 - H = 0.97 Å and Csp2 - H = 0.93 Å, and constrained to ride on their parent atoms, with Uiso(H) = 1.5 Ueq(C). The positions of H atoms attached to O and N atoms were localized in difference Fourier maps, and refined isotropically.

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.
