چکیده
The title compound, {[Mn(3)(C(10)H(5)O(7))(2)(C(10)H(8)N(2))(2)]·H(2)O}(n), was synthesized under hydro-thermal conditions. Six carboxyl-ate groups of six 5-(carboxyl-atometh-oxy)benzene-1,3-dicarboxyl-ate anions (OABDC(3-)) join three Mn(II) ions into a trinuclear centrosymmetric [Mn(3)(μ(2)-COO)(6)] unit with one Mn site situated on a centre of inversion. The latter Mn(II) ion exhibits a distorted MnO(6) coordination, whereas the other Mn(II) ion has a trigonal-bipyramidal MnN(2)O(3) coordination environment resulting from three carboxylate O atoms and the two N atoms of the bipyridine ligand. Adjacent units are linked to each other by OABDC(3-) ligands into a layer parallel to (010). Within the layer, O-H⋯O hydrogen-bonding inter-actions involving the uncoordinated and half-occupied water mol-ecule and the free carboxyl-ate O atoms are observed. The layers stack along [010], constructing a three-dimensional structure through π-π inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.473 (5) Å.
