Synthesis and Spectroscopic Studies of Ru(II) Complexes of 1,2,4-Triazoles, 1,2,4-Triazines and Pyrimidine Derivatives

Treatment of the dichlorodicarbonyl ruthenium(II) [Ru(CO)2Cl2]n with bidentate 1,2,4-triazoles, 1,2,4-triazines and pyrimidine derivatives in refluxing ethanol or in THF yielded stable, octahedral yellow or pale-yellow solids. All the complexes have been characterized by IR, 1 H NMR spectroscopy and elemental analyses.
