In order to model processes of chemisorption in organic salts formed between dinitrobenzoic acids (DNBH) and secondary amines (R(2)NH), a series of compounds of composition [M(II)(3,5-DNB)(2)(DMSO)(2)(H(2)O)(2)] (where M(II) is Zn, Cu, Ni or Co, 3,5-DNB is the 3,5-dinitrobenzoate ion, and DMSO is dimethyl sulfoxide) have been prepared. In diaquabis(dimethyl sulfoxide)bis(3,5-DNB)zinc(II), [Zn(C(7)H(3)N(2)O(6))(2)(C(2)H(6)OS)(2)(H(2)O)(2)], the 3,5-DNB ions and molecules of DMSO are monodentate ligands that are coordinated to the Zn atom through their O atoms. These ligands, together with two molecules of water, form a slightly distorted octahedral coordination environment for the Zn atom, which lies on a center of symmetry.
