Abstract

Reactions of laser-ablated ruthenium atoms with carbon monoxide and hydrogen in solid argon produce the unsaturated ruthenium carbonyl dihydride H2Ru(CO)(2) and the hydrogen complexes (H-2)(lambda)RuCO (x = 1, 2). The observed absorption bands of the reaction products are identified by isotopic substitution and reproduced well by DFT calculations of vibrational fundamentals. The growth of bands due to H2Ru(CO)(2) and (H-2)-RuCO during annealing in solid argon indicates that ruthenium monocarbonyl is coordinated with HLto form the dihydrogen complex (H-2)RuCO, while H2Ru(CO)(2) is formed fromthe (II)RuCO complex inserting into (Hz) upon coordinating with another CO. Weak bands due to H2Ru(CO)(3) and H2Ru(CO)(4) are also observed.
