Two new mononuclear mixed-ligand ruthenium(II) complexes with acetylacetonate ion (2,4-pentanedionate, acac) and functionalized bipyridine (bpy) in position 4, [Ru(bpyBr)2(acac)](PF6) (2; bpyBr = 4-Bromo-2,2’-bipyridine, acac = 2,4-pentanedionate ion) and [Ru(bpyOH)2(acac)](PF6) (3; bpyOH = 4-[2-methyl-3-butyn-2-ol]-2,2’-bipyridine) were prepared as candidates for building blocks. The 1H NMR, 13C-NMR, UV-Vis, electrochemistry and FAB mass spectral data of these complexes are presented.
