title: Bis(mu-6-hydroxypicolinato)-mu-oxo-bis[dipyridinemanganese(III)] monohydrate.
abstract: The title compound, [Mn2(mu-O)(C6H3NO3)2(C5H5N)4].H2O, was isolated from the reaction of 2,6-pyridinedicarboxylic acid with [Mn12O12(CH3COO)16(H2O)4] in pyridine. The dimanganese complex has twofold symmetry; the MnIII atoms are bridged by one oxo and two amidate ligands and show compressed octahedral Jahn-Teller distortion. The molecular packing comprises a three-dimensional structure constructed by means of extensive intermolecular interactions, including three kinds of hydrogen bonds and pi-pi interactions.
