چکیده
In the title compound, [FeNa(2)(SO(4))(2)(H(2)O)(4)], the Fe(2+) cation is situated on a centre of inversion and is hexa-coordinated by four O atoms from water mol-ecules and two O atoms from two sulfate anions in an octa-hedral geometry. The coordination environment of Na(+) comprises six O atoms in a more distorted octa-hedral arrangement, with Na-O distances between 2.368 (1) and 2.612 (1) Å. The structure contains an extensive three-dimensional network of O-H⋯O hydrogen bonds.

In the title compound, [Fe(SO(4))(C(10)H(7)N(3)S)(2)(H(2)O)], the Fe(II) cation is sixfold coordinated by four N atoms from two 2-(1,3-thia-zol-4-yl)-1H-benzimidazole ligands, one water O atom and one O atom of the sulfate dianion within a slightly distorted octa-hedral geometry. The cations and anions are connected by N-H⋯O and O-H⋯O hydrogen bonds into layers in the ab plane.
