【 摘 要 】

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.
