Synthesis and characterization of novel (cyclopentadienyl) nitroruthenium complexes

Ruthenium complexes of the type [Ru(Cp)(L) 2 (NO 2 )] (Cp=η 5 −C 5 H 5 ; L=PPh 3 , 1/2 dppe (1,2-bis(diphenylphosphino)ethane), 1/2 dppm (bis(diphenylphosphino)methane), 1/2-ampe(1,2-bis(dimethylphosphino)ethane)) were synthesized in three-step syntheses starting with RuCl 3 •3H 2 O. Characterization of these complexes was accomplished through UV-vis, 1 H NMR, and IR spectroscopies, cyclic voltammetry, and elemental analysis
