Abstract

Complexes of 3d transition metal chlorides with dinitrobenzoic acids (DNBH) and secondary amines have been synthesized in order to model processes of chemisorption of organic salts by metal surfaces. A series of compounds of composition (AmH)2[MCl2(DNB)2] (where M = ZnII, CuII; AmH+ is the cation of piperidine PipH+ = C5H10NH2+ or diethylamine DaH+ = C4H10NH2+) have been prepared, the structure of the piperidinium salt of the Zn/3,5-DNB complex anion being authenticated by X-ray crystallography. In the title compound, (C5H12N)2[ZnCl2(C7H3N2O6)2], the Zn atom is four-coordinated. The DNB ligand behaves as a monodentate ligand via an O atom of the carboxylate group, the other carboxylate O atom being hydrogen bonded to one of the ammonium H atoms. The other ammonium H atom of the two cations links to the coordinated chlorides, one within the complex and the other across an inversion center, so forming a dimer. biblio
