title: Poly[[tris-(μ(3)-2-oxidopyridinium-3-carboxyl-ato)manganese(II)sodium(I)] monohydrate].
abstract: In the crystal structure of the title compound, {[MnNa(C(6)H(4)NO(3))(3)]·H(2)O}(n), the Mn(II) cation is located on a threefold rotation axis and is chelated by three 2-oxidopyridinium-3-carboxyl-ate (opc) anions in an octa-hedal coordination. The Na(I) cation is located on a threefold rotation axis and is surrounded by six O atoms from three opc anions. The opc anions link the Mn and Na cations, forming a three-dimensional polymeric structure. The uncoordinated water mol-ecule, located on a threefold rotation axis, is equally disordered over two sites. The three-dimensional network is consolidated by N-H⋯O hydrogen bonds.
