Poly[hexa-μ-acetato-bis­(dimethyl sulfoxide)­trimanganese(II)]

In the title complex, [Mn(3)(CH(3)CO(2))(6)(C(2)H(6)SO)(2)](n), the Mn(II) ions exhibit similar MnO(6) octa­hedral coordination geometries but with different coordination environments. One type of Mn(II) ion is surrounded by five acetate groups and a terminal dimethyl sulfoxide group, while the other lies on a twofold axis and is coordinated by six O atoms from three symmetry-related acetate ions. The acetate anions exhibit three independent bridging modes, which flexibly bridge the Mn(II) ions along the c-axis direction, forming an infinite chain structure; the chains are further inter­connected through weak C—H⋯O and C—H⋯S hydrogen-bonding inter­actions.
