Sažetak
Over the past few decades, there has been a constant growing interest for novel metal−organic coordination polymers due to their potential applications as functional materials in diverse fields such as hydrogen storage and gas separation, heterogeneous catalysis, luminescence and ion exchange, sensors, or supramolecular magnetism. In the design and synthesis of heteropolynuclear complexes an important role belongs to the oxalate C2O42− anion because of its various possibilities of coordination to metal centers and the ability to mediate magnetic interactions between paramagnetic metal ions. In the search for suitable synthetic routes leading to novel and promising polynuclear species, it has been of considerable importance to find convenient mononuclear complexes that could be used as ligands toward other metal ions. The tris(oxalato)metalate anions [M(C2O4)3]3− (M = trivalent metal) have been widely used as ligands toward metal ions in the preparation of extended multifunctional systems. The dimensionality and nuclearity of these oxalate- bridged compounds are controlled by a templating counterion, namely its size, charge and geometry as well as synthetic conditions (Jurić et al., 2013). In general, metal–organic coordination systems have recently been used as molecular precursors for the preparation of the mixed-metal oxides by their thermal decomposition. This method of obtaining oxide materials, compared with conventional methods, has several advantages. The C2O42− anion easily decomposes to the vapour phases CO2 and CO, by the low-temperature routes, and hence, heterometallic oxalate complexes have already been used for the single-step preparation of mixed metal oxides (Androš et al., 2013). As a continuation of our magneto- structural studies concerning the polynuclear transition-metal complexes, new heterometallic 3D oxalate-bridged coordination polymers {; ; ; ; [M(bpy)3] [Mn2(C2O4)3]·H2O}; ; ; ; n [M = Co2+ (1), Cu2+ (2) ; bpy = 2, 2′-bipyridine] have been prepared and, in addition to the single-crystal X-ray study, characterized by magnetization measurements. The ability of compounds 1 and 2 to act as the single-source precursors for the formation of the spinel oxides was investigated by the thermal analysis (TGA and DTA) and X-ray powder diffraction.
