[Show abstract][Hide abstract] ABSTRACT:
The dinuclear complex in the title compound, [Mn2(C16H6N2O8)(H2O)10]·4H2O, lies on an inversion center. Two delocalized carboxylate groups are each connected in a monodentate fashion to two similar pentaaquamanganese units, whereas the other two localized carboxylate groups are uncoordinated. The metal ion has octahedral coordination, with the O atom of a carboxylate group and three coordinated water molecules forming the equatorial plane [Mn—OCOO = 2.143 (4) Å] and two water molecules occupying the axial positions. The architecture is further consolidated by extensive hydrogen bonds for which coordinated water molecules serve as donors or acceptors.
