5-Dp)Ru(PPh3)2H (Dp = C8H9, 1,2-dihydropentalenyl) was synthesized in 90% yield by reaction of (η5-Dp)Ru(PPh3)2Cl with sodium formate. (η5-Dp)Ru(PPh3)2H was characterized by 1H and 31P NMR spectroscopy and IR spectroscopy. The Ru–H appears in the 1H NMR spectrum upfield at −11.6 ppm, indicative of a metal hydride. In the IR spectrum, the νRu–H was observed at 1920 cm−1. The solid-state structure of (η5-Dp)Ru(PPh3)2H (1) was determined by X-ray crystallography. Compound 1 has similar structural parameters to (η5-Cp)Ru(PPh3)2H and (η5-Ind)Ru(PPh3)2H.
