Structure, reactivity, and computational studies of a novel ruthenium hydrogen sulfide dihydride complex.
Addition of 1 atm of H(2)S to [Ru(IMes)(2)(CO)(EtOH)H(2)] (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene) affords the air-stable hydrogen sulfide dihydride complex, [Ru(IMes)(2)(CO)(H(2)S)H(2)] 2. Treatment of 2 with excess H(2)S leads to formation of the 16-electron bis-hydrosulfido complex, [Ru(IMes)(2)(CO)(SH)(2)] 3. Preliminary studies show that 3 reacts with both H(2) and CO in solution as well as in the solid state. Both 2 and 3 have been structurally characterized
