Complexes of ruthenium(III) with N,N′-disalicylidene-l,2-phenylenediamine (H2dsp), N,N′-disalicylidene-3,4-diaminotoluene (H2dst), 4-nitro-N,N′-disalicylidene-1,2-phenylenediamine (H2ndsp) and N,N′-disalicylidene ethylenediamine (H2salen) have been prepared and characterized by elemental analysis, molar conductivity, spectral methods (mid-infrared, 1H NMR and UV–vis spectra) and simultaneous thermal analysis (TG and DTG) techniques. The molar conductance measurements proved that all these complexes are non-electrolytes. The electronic spectra measurements were used to infer the structures. The IR spectra of the ligands and their complexes are used to identify the type of bonding. The kinetic thermodynamic parameters such as: E*, ΔH*, ΔS* and ΔG* are estimated from the DTG curves. The four ligands and their complexes have been studied for their possible biological antifungal activity.
