Abstract

Two new Tl+ and K+ complexes of 3,5-dinitrobenzoic acid (HDNB), [Tl(μ-DNB)] n and [K(μ-DNB)(μ-HDNB)] n have been synthesized and characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy. Determination of the structure of the [K(μ-DNB)(μ-HDNB)] n and [Tl(μ-DNB)] n by X-ray crystallography shows that there are nine coordinate K atoms (KO9) and eight coordinate Tl atoms (TlO8). The [Tl(μ-DNB)] n and [K(μ-DNB)(μ-HDNB)] n complexes are 2D and 3D coordination polymers, respectively.
