Dimethyl pyridine-2,6-carboxylate (L) was prepared by refluxing pyridine-2,6-dicarbonyl dichloride in methanol. The reactions of L with Ca(II), Sr(II), and Ba(II) salts and with cobalt(II) thiocyanate resulted in the formation of three heterometallic complexes: [CaL3][Co(NCS)4] (I), [SrL3][Co(NCS)4] (II), and [BaCoL3(μ-NCS)2(NCS-κN)2] (III). The composition and structure of compounds L and I–III were determined by elemental analysis, infrared spectroscopy, and X-ray diffraction (CCDC nos. 2166019–2166022, respectively). It was found that isostructural Ca(II) and Sr(II) compounds are ionic and are formed by the [CaL3]2+ and [SrL3]2+ complex cations and [Co(SCN)4]2– complex anion, while the Ba(II) derivative is a molecular complex in which [BaL3]2+ and [Co(NCS)4]2– moieties are linked by two (NCS)– bridging units of the complex anions. In any of the three compounds, three tridentate L ligands are coordinated to the alkaline earth metal ion. |
