title: Poly[tetra-aqua-(μ(4)-benzene-1,3,5-tri-carboxyl-ato)sodium(I)zinc(II)].
abstract: In the title compound, [NaZn(C(9)H(3)O(6))(H(2)O)(4)](n), the Zn(II) atom is six-coordinated by four O atoms from two different benzene-1,3,5-tricarboxyl-ate anions and two water O atoms in a distorted tetragonal-bipyramidal geometry and the Na(I) atom is five-coordinated by three O atoms from three different benzene-1,3,5-tricarboxyl-ate anions and two water O atoms in a distorted trigonal-bipyramidal geometry. The benzene-1,3,5-tricarboxyl-ate anion bridges two Zn(II) atoms and two Na(I) atoms, resulting in the formation of a two-dimensional layer structure. Inter-molecular O-H⋯O hydrogen-bonding inter-actions generate a three-dimensional superamolecular structure.
