Abstract: The title compound, [Mn(C₆H₂O₄S)(C₁₀H₈N₂)(H₂O)₃]·0.5C₁₀H₈N₂·3H₂O or [Mn(tdc)(bpy)(H₂O)₃]·3H₂O·0.5(bpyn) (tdc is thiophene-2,5-dicarboxylate, bpy is 2,2'-bipyridine and bpyn is 4,4'-bipyridine), crystallizes in space group P. Complex molecules are linked into one-dimensional chains, running along the b axis, by hydrogen bonds between the coordinated aqua ligands and uncoordinated carboxylate groups of tdc. Double-stranded chains consist of two of the one-dimensional chains and uncoordinated centrosymmetric bpyn molecules, connected by hydrogen bonds between N atoms of the bpyn molecules and coordinated aqua ligands. These double chains are further assembled into layers parallel to the ab plane, which extend into three-dimensional networks via hydrogen bonds between the coordinated and uncoordinated water molecules, and O atoms of tdc.
