Abstract:
The solvent free reaction route produces coordination polymers that have a dimensionality of the linkage, which is increasing with the thermal energy. The synthesis of the 3D metal organic framework (MOF) structure (3)(infinity)[Eu(Btz)(2)] marks the final thermal reaction step within the system europium/1H-1,2,3-benzotriazole. It can be obtained by a reaction of the metal with a melt of benzotriazole above 230 degrees C or from thermal treatment of the ID coordination polymer (1)(infinity)[Eu(Btz)(2)(BtzH)(2)] (Btz(-) = 1,2,3-benzotriazolate anion, C6H4N3-; BtzH = 1H-1,2,3-benzotriazole, C6H5N3), which is formed first at about 100 degrees C from the same reagents. In addition to the trivalent rare earth ions it can thus be shown that also divalent Eu-II together with benzotriazole exhibits transformation of a ID coordination polymer into a 3D MOF. The homoleptic framework (3)(infinity)[Eu(Btz)(2)] exhibits a high thermal stability (525 degrees C) for an exothermically decomposing coordination compound. As (3)(infinity)[Eu(Btz)(2)] is always obtained as a microcrystalline product, structure solution and refinement were achieved by Xray powder techniques. For further characterization Eu-151-Mossbauer, IR, and Raman spectroscopy as well as micro and thermal analysis were carried out.
