Poly[tetraaqua(μ4-benzene-1,3,5-tricarboxylato)sodium(I)zinc(II)]

Abstract

In the title compound, [NaZn(C9H3O6)(H2O)4]n, the ZnII atom is six-coordinated by four O atoms from two different benzene-1,3,5-tricarboxylate anions and two water O atoms in a distorted tetragonal-bipyramidal geometry and the NaI atom is five-coordinated by three O atoms from three different benzene-1,3,5-tricarboxylate anions and two water O atoms in a distorted trigonal-bipyramidal geometry. The benzene-1,3,5-tricarboxylate anion bridges two ZnII atoms and two NaI atoms, resulting in the formation of a two-dimensional layer structure. Intermolecular O—H...O hydrogen-bonding interactions generate a three-dimensional superamolecular structure.
