Synthesis and reactivity of mercury-bridged transition-metal clusters. 4. Reactivity of (μ3-η2-C2-t-Bu)(CO)9Ru 3HgMo(η5-C5H5)(CO)3

The thermolysis, photolysis, and phosphine substitution reactions of [Ru3(μ3-η2-C2-t-Bu)(CO) 9] (μ3-Hg)[Mo(η5-C5H5)(CO) 3] (I) and its derivatives have been studied. Redistribution reaction between the two different monophosphine-substituted derivatives of I show that the Hg-Mo bond is relatively labile compared to the μ-Hg-Ru2 bond. Photolysis of I yields the product (μ3-η2-t-Bu)Ru2Mo(η 5-C5H5)(CO)8 (VII), a new triangular mixed-metal cluster. The solid-state structure of VII was determined by X-ray crystallography. Compound VII crystallizes in the monoclinic space group P21/c with a = 9.116 (2) A?, b = 15.982 (3) A?, c = 13.510 (5) A?, β = 108.81 (2)°, V = 2139.1 (8) A?3, and dcalcd = 2.075 g/cm3 for Z = 4. Least-squares refinement led to final agreement indices R = 0.018 and Rw = 0.024 for 3217 observed reflections. An investigation of the ligand dynamics of VII by variable-temperature 13C NMR revealed that there is no intermetallic scrambling of carbonyls around the Ru2Mo triangle, but a restricted edge-hopping motion of the coordinated acetylide between the two Ru-Mo edges is observed.
