54 Chapter 3 Figure 3.20. (a) XANES spectra of the Ru II,III -BTC 1 and Ru II,II -BTC (5) in comparison with correspondingly employed Ru-precursors (SBU-a and –e) and the commonly used reference (RuCl 3 ); (b) XANES spectra of Ru II,II -BTC (5) and the employed precursor Ru II,II -SBU ([Ru 2 (OOCCH 3 ) 4 ],SBU-e). The vertical line stands for the same position of edge jump.

Violet circle- Ru II,II -BTC; orange triangle- Ru II,III -BTC. 3.2.3 Conclusions Moving from the usage of the mixed-valence Ru II,III -SBUs to the mono-valence Ru II,II -SBU in CSA, a Ru-analog ([Ru3(BTC)2]n∙(AcOH)2.3) of [Cu3(BTC)2]n has been obtained and characterized. Interestingly, XANES spectra suggest Ru II,II sites being present in the structure of the obtained sample 5. Moreover, the BET surface area of this material is the highest (1173 m 2 /mmol) among of all reported so far Ru-BTC MOFs and quite comparable with that of HKUST-1 (1049 m 2 /mmol). Thus, Ru II,II -BTC hold a huge perspectives for various applications in sorption and catalysis. Even more, obtained results are important for the following studies on related but more complex defect-engineered Ru-MOFs (see Chapter 4), and elaborated here Ru II,II -SBU is a good candidate for the synthesis of Rubased MOFs.
