Mononuclear [Ru(II)(tptz)(acac)(CH3CN)]ClO4 (ClO4) and mixed-valent dinuclear [(acac)2Ru(III){(mu-tptz-Eta+)-}Ru(II)(acac)(CH3CN)]ClO4 (ClO4; acac = acetylacetonate) complexes have been synthesized via the reactions of Ru(II)(acac)2(CH3CN)2 and 2,4,6-tris(2-pyridyl)-1,3,5-triazine (tptz), in 1:1 and 2:1 molar ratios, respectively. In ClO4, tptz binds with the Ru(II) ion in a tridentate N,N,N mode (motif A), whereas in ClO4, tptz bridges the metal ions unsymmetrically via the tridentate neutral N,N,N mode with the Ru(II) center and cyclometalated N,C- state with the Ru(III) site (motif F). The activation of the coordinated nitrile function in ClO4 and ClO4 in the presence of ethanol and alkylamine leads to the formation of iminoester ClO4 and ClO4) and amidine ClO4) derivatives, respectively. Crystal structure analysis of ClO4 reveals the formation of a beautiful eight-membered water cluster having a chair conformation.
