Description
Summary:[Display omitted] •Slow diffusion is a powerful synthetic strategy to produce single crystals;•1,3,5-tris(4-carboxylphenyl)benzene can coordinate to the metal center with diverse coordination modes;•Auxiliary ligands can play an important role in directing the topology of the system;•Cu(II) ions are interesting systems with great potential in quantum computing. In this contribution, we report the crystal structure and magnetic properties of a new copper dimer prepared through the reaction of CuCl2·6H2O with the pre-ligands H3BTB (1,3,5-tris(4-carboxylphenyl)benzene) and dmdpy (5–5′dimethyl-2,2′dipyridyl), with the stoichiometric ratio 1:2:1, respectively. The dinuclear complex [Cu2(HBTB)2(dmdpy)2]•2H2O presents two pentacoordinated Cu(II) ions connected by the polycarboxylate HBTB ligand. The study of the magnetic properties revealed no significant magnetic interactions between the Cu(II) ions.
