Crystal structure and thermal properties of bis[μ-2-(methoxycarbonylhydrazinylidene)acetato-κ(3) N (1),O:O]bis[diaqua(thiocyanato-κN)manganese(II)] tetrahydrate
The title compound, [Mn(2)(C(4)H(5)N(2)O(4))(2)(NCS)(2)(H(2)O)(4)]·4H(2)O (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 so...

Sumario: | The title compound, [Mn(2)(C(4)H(5)N(2)O(4))(2)(NCS)(2)(H(2)O)(4)]·4H(2)O (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 M (2)O(2) 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. |
