| Abstract: | Several new hexa-coordinated ruthenium(II) and penta-coordinated rhodium(I) complexes of the types RuCl(CO)(PPh 3 ) 2 (TSC)], RuH(CO)(PPh 3 ) 2 (TSC)], and Rh(PPh 3 ) 3 (TSC)] (where TSC = anion of thiosemicarbazone Schiff bases) have been prepared by the reactions of RuHCl(CO)(PPh 3 ) 3 ], RuH 2 (CO)(PPh 3 ) 3 )], and RhH(PPh 3 ) 4 ] with thiosemicarbazones of 2-furaldehyde (H-FTSC), thiophene-2-carboxaldehyde (H-TCTSC), p-anisaldehyde (H-ATSC), piperonaldehyde (H-PTSC), and cyclohexanone (H-CTSC). All the new complexes obtained have been characterized on the basis of elemental analysis, IR, 1 H NMR, 31 P NMR, and electronic spectral data. |
