Replacement of the dppm ligand in (η5-C5H4(CH2)2NMe2H+)Ru(dppm)H with two less donating triphenyl phosphite ligands reduces the strength of the intramolecular Ru−H···H−N dihydrogen bond to such an extent that it is hardly evidenced by NMR measurements. Unlike its dihydrogen-bonded dppm analogue, the triphenyl phosphite complex (η5-C5H4(CH2)2NMe2H+)Ru(P(OPh)3)2H shows no catalytic activity for reduction
