In order to model processes of chemisorption in organic salts formed between dinitrobenzoic acids (DNBH) and secondary amines (R2NH), a series of compounds of composition [MII(3,5-DNB)2(DMSO)2(H2O)2] (where MII 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(C7H3N2O6)2(C2H6OS)2(H2O)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.
