Complexes of 2,3-dimethoxybenzoates of Co(II), Ni(II) and Cu(II) have been synthesized as hydrated or anhydrous polycrystalline solids and characterized by elemental analysis, IR, FIR and electronic spectroscopy, magnetic studies and X-ray diffraction measurements. The carboxylate groups bind as monodentate or symmetrical, bidentate chelating and bridging ligands. The thermal stabilities were determined in air. When heated they dehydrate to form anhydrous salts which are decomposed to the oxides of the respective metals. The magnetic susceptibilities of the complexes were measured over the range 77?300 K and the magnetic moments were calculated. The results show that the complexes of Ni(II) and Co(II) are high-spin complexes and that of Cu(II) forms a dimer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
