In the title compound, C10H9N2+·C6H4NO5S−, the dihedral angle between the aromatic rings of the cation is 9.42 (7)°. In the crystal, the anions and cations are linked by C—H⋯O and N—H⋯O hydrogen bonds, generating R21(5) and R44(14) rings, respectively. These hydrogen bonds also provide packing along [110].

1.944 g Mn-BSA (3 mmol) was dissolved in 10 ml of water and a solution of bipyridine (0.937 g, 6 mmol) in 3 ml e thanol was added into the solution. After stirring for 10 minutes, the solution was left for crystallization and a precipitate of Mn(OH)2 was obtained and resolved again with the addition of 2 ml concentrate HCI into the mixture. Two different forms of crystals, one has a yellow colour while other is colurless, were grown after one day. The crystals were washed with slightly acidic water to separate from each other. The yellow one was resolved whereas the colourless one was not within the acidic solution. Transparent square-shaped crystals of X-ray quality were dried in vacuo.
The H atom bonded to N atom was located in Fourier map and refined isotropically. Other H atoms were placed in calculated positions, with C—H = 0.93 Å, and refined in riding model, with Uiso(H) = 1.2Ueq(C).

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. |

In this study, we have examined the title compound obtained by synthesize of the meta-nitro benzene sulfonic acid sodium salt and the bipyridine. The 2,2'-bipyridine and its fused analogues are exhibit important application in coordination and supramolecular chemistry (Grummt et al., 2004; Branowska et al., 2005; Zhang et al., 2007; Kavitha et al., 2006) while aromatic sulfonates draw attention because of their industrial applications as surfactants, dyes, fuel and lubricant detergents (Sharma et al., 2004; Vembu et al., 2009).
The asymmetric unit of the title compound contains protonated 2,2'-bipyridin-1-ium cation and deprotonated m-nitrobenzenesulfonate anion. A perspective unit of the asymmetric unit is presented in Fig. 1. In the asymmetric unit, the mean planes of the anionic (except O atoms bounded S atom) and cationic moieties oriented to each other with 6.88 (5)°. However, the protonated and deprotonated rings of bipyridinium oriented to the aromatic ring of anionic moiety with 9.16 (5)° and 4.79 (5)°, respectively. The two pyridine rings forming bipyridinium moiety are slightly twisted by 9.42 (7)°.
For the bipyridinium cation, the N—C bond distances are in the range 1.331 (2) Å-1.3446 (18)Å and, as expected, the protonated part of the bipyridinium has slightly different bond lengths and angles than non-protonated part. The C1—N1—C5 angle [123.75 (13)°] is larger than the C6—N2—C10 angle [117.10 (14)°].
The S—O bond distances for m-nitrobenzenesulfonate are in the range 1.4370 (13) Å-1.4466 (13) Å, while the adjacent O—S—O angles are in the range 112.77 (8)–113.72 (8)°. The nitro group is slightly deviated from planarity with the dihedral angle of 2.98 (16)° between the benzene and nitro moieties.
The anionic and cationic moieties are linked by C—H···O and N—H···O type hydrogen bonds. In the structure, the nitrobenzene sulfonate anion acts as donor while bipyridinium cation acts as acceptor. The C1—H1···O4i and C2—H2···O4i interactions constitute a bifurcated acceptor bonds generating R21(5) rings in graph-set notation (Bernstein et al., 1995). It is also found that the R44(14) ring motives are generated by the N1—H1A···O3 and C1—H1···O4i hydrogen bonds (Fig. 2). These adjacent rings are provide packing along to the direction [110]. Furthermore, the intra-molecular N1—H1A···N2 hydrogen bonds generate S(5) ring motives (Fig. 1). Geometric details of hydrogen bonds are given in Table 1.
