Abstract top

In the title salt, C10H10N22+·2C7H4NS2-, the complete 4,4'-bipyridine-1,1'-diium dication is generated by a center of symmetry. In the crystal, N-H...N hydrogen bonds are observed between the cations and anions.

Comment top

The 4,4'-bipyridine lignad is ideal for forming supramolecular structures. Many examples in coordination with multifarious metals are observed (Biradha et al., 1999; Tong et al., 2000; Tao et al., 2000; Ren et al., 2004; Xu et al., 2012). However, to our best knowledge, only a few Ag(I)-Hmbt (Hmbt = 2-mercaptobenzothiazole) framework structures have been reported (Chen et al., 2010). In our work synthesizing an Ag(I)-Hmbt complex containing the 4,4'-bipyridine, the title compound, (I), (C10H10N2).(C7H4NS2)2 was unexpectedly obtained.

The crystal structure of the title compound, (I), consists of one mbt (mercaptobenzothiazole) anion and one 4-pyridyl unit containg a center of symmetry which upon expansion produces a 4,4'-bipyridine-1,1'-diium cation and two mbt cations in the asymmetric unit (Fig. 1). Crystal packing reveals that N—H···N intermolecular hydrogen bonds are observed between the centrosymmetric 4,4'-bipyridine-1,1'-diium cation and two mbt anions (Fig. 2; Table 1). These observed hydrogen bonds are similar to those reported in a similar and related compound, (C10H8N2)(C2H3N3S2)2, (Deng et al., 2005).

Experimental top

A mixture of AgBr (0.2 mmol) and 2-mercaptobenzothiazole (0.2 mmol) in MeOH and CH2Cl2 (10 mL, v/v = 1:1) was stirred for 2 h and triphenylphosphine (PPh3)(0.2 mmol) was added to the mixture which was stirred for another 5 h. The insoluble residues were removed by filtration. The filtrate was then evaporated slowly at room temperature for a week to yield colorless crystalline products. Anal. Calc. for C24H18N4S4: C, 58.70; H, 3.67; N, 11.41. Found: C, 58.49; H, 3.79; N, 11.22%. Melting point: 427–431°K.

Refinement top

All H atoms were located in the calculated sites and included in the final refinement in the riding model approximation with displacement parameters derived from the parent atoms to which they were bonded (Uiso(H) = 1.2Ueq). C—H hydrogen atoms (aromatic) were included with distance set to 0.93 Å and amide N—H hydrogen atoms were included with distance set to 0.86 Å.

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.
