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 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.
