Tetra-aqua-bis-[4-(pyrazin-2-ylsulfanylmeth-yl)benzoato]manganese(II) dihydrate.

ABSTRACT: The title compound, [Mn(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)]·2H(2)O, has been synthesized with a flexible asymmetrical bridging ligand, 4-(pyrazin-2-ylsulfanylmeth-yl)benzoic acid (Hpztmb). The Mn(II) ion exhibits a centrosymmetric octa-hedral geometry involving two carboxyl-ate O atoms of two different pztmb ligands and four O atoms of four coordinated water mol-ecules. The packing shows a three-dimensional supra-molecular network via O-H?O and O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.884?(8) and 4.034?(8)?Å] between the benzene ring of one pztmb anion and the pyrazine ring of an adjacent anion.
