摘要：
The title salt, [Fe II (C4H3ClN2)(2)(H2O)(4)](C7H7O3S)(2), contains a complex cation with point group symmetry 2/m. The high-spin Fe-II cation is hexacoordinated by four symmetry-related water and two N-bound 2-chloropyrazine molecules in a trans arrangement, forming a distorted FeN2O4 octahedron. The three-dimensional supramolecular structure is supported by intermolecular O-H center dot center dot center dot O hydrogen bonds between the complex cations and tosylate anions, and additional pi-pi interactions between benzene and pyrazine rings. The methyl H atoms of the tosylate anion are equally disordered over two positions.
