7.2 Experimental data on chapter 3
All chemicals (RuCl3·xH2O, LiCl, AgSO4, NaBPh4, AgBF4, pivalic acid, benzene-1, 3, 5-
tricarboxylic acid (H3BTC)) and all solvents (CH3COOH, H2O, CH3OH, EtOH, acetic
anhydride, acetone and hexane) were used as commercially received unless otherwise
noted. Tetrahydrofuran (THF) used in the synthesis of SBU-c was catalytically dried,
deoxygenated, and saturated with argon using an automatic solvent purification system
from MBraun.
7.2.1 Synthesis of the ruthenium precursors ([Ru2(OOCR)4X] and
[Ru2(OOCCH3)4]A)
Scheme 7.1. Preparation of the Ru-SBUs (SBU-a to SBU-d) used for MOF syntheses.
[Ru2(OOCCH3)4Cl] (SBU-a)
This compound was prepared using the method reported in the literature with slight
modification. [202] RuCl3·xH2O (0.5 g, 2 mmol) and LiCl (0.5 g, 11.9 mmol) were mixed in
one flask. Then glacial acetic acid (17.5 ml) and acetic anhydride (3.5 ml) were added.
Subsequently, the mixture was refluxed for 24 h. The resulting red-brown precipitate was
collected, washed several times with acetone, and dried under ambient conditions first
and then under dynamic vacuum for at least 4 h (Yield: 0.33 g).
