摘要：

Self-assembled metalla-rectangle [(eta(6)-p-cymene)(4)Ru-4(C6H2O4)(2)(2)(2)](CF3SO3)(4) (3) was prepared by the reaction of dinuclear half-sandwich ruthenium(II) complex [Ru-2(eta(6)-p-cymene)2(C6H2O4)Cl-2] (1) with a bis-pyridyl-bis-amide linker (2) in methanol in the presence of AgO3SCF3. This new stable discrete 2D structure was fully characterized by analytical techniques including elemental analysis, FT-IR spectroscopy, H-1 NMR, C-13 NMR, H-1-H-1 COSY, H-1-C-13 HMQC spectroscopy, and HR-ESI-MS spectrometry. A UV-Vis study was also carried out for both ruthenium complex (1) and metalla-rectangle (3). The UV-Vis absorption studies and Job's plot of multi-carboxylate anions (sodium oxalate and sodium citrate) in presence of metalla-rectangle 3 showed adduct formation in a 1:1 fashion.
