Synthesis and characterization of a dinuclear (Hedta)Ru(III) complex.

A ruthenium(III) complex containing ethylenediaminetetraacetate (edta), [{Ru(Hedta)}2(Pyz)] · 8H2O (1) (Pyz = pyrazine), has been synthesized by the reaction between K[Ru(Hedta)Cl] · 1.5H2O and pyrazine. The structure of the complex was determined by single X-ray diffraction. Complex 1 crystallizes in the triclinic space group P1 with a = 7.293(9) Å, b = 10.575(14) Å, c = 12.742(16) Å, α = 104.044(19)°, β = 91.893(19)°, γ = 93.35(2)°, Z = 1. The product was also characterized by IR, UV-Vis, EPR spectrum and magnetic techniques. [ABSTRACT FROM AUTHOR]
