The complexes [(Cp)Ru(CO)(3)](+) and [(Ind)Ru(CO)(3)](+) were subjected to chemical, electrochemical, and spectroelectrochemical investigations in an attempt to gauge their similarity to [(Cp)Fe(CO)(3)](+) and [(Ind)Fe(CO)(3)](+). While the Fe complexes exhibited reversible electrochemical behavior-the indene analogue exhibiting a so-called "inverse indenyl effect"-the Ru complexes exhibited limited electrochernical reversibility, even at -30 degrees C and higher scan rates. The formation of the hydride complexes [(Cp)Ru(CO)(2)H] and [(Ind)Ru(CO)(2)H] was observed via H-1 NMR and IR. The X-ray crystal structure of [(Ind)Ru(CO)(3)](+) is presented here for the first time.
