Abstract

The title compound, [Mn₂(C₄H₅N₂O₄)₂(NCS)₂(H₂O)₄]·4H₂O (I), exists as a centrosymmetric dimer. Each dimeric unit consists of tridentate (O,O,N)-chelating Schiff bases with symmetry-maintained μ-O-bridged carboxylate anions, terminally bound thiocyanate anions, and ligated and solvated water molecules. The complex exhibits a distorted octahedron geometry and the centrosymmetric μ-O-bridged carboxylate anions connect the two manganese atoms to form an M₂O₂ ring. In the crystal, the molecules are interlinked via strong N - H⋯O and O - H⋯O hydrogen-bonding contacts and weak O - H⋯S intermolecular interactions, forming a three-dimensional molecular network.
