Metal clusters in catalysis. The reactivity of alkyne-and vinylidene-substituted homo- and hetero-metallic clusters towards molecular hydrogen in homogeneous conditions
reactivity of alkyne- and vinylidene-substituted clusters towards molecular hydrogen in homogeneous conditions has been studied by means of GC and GC/MS techniques. The reactivity of the homo- and hetero-metallic cluster frames (containing nickel and one of the irontriad metals) is discussed, as well as that of the coordinated ligands. Under hydrogen the cluster cores are modified, sometimes as a part of
Multi-site bonded hydrocarbyls on osmium clusters. The reactions of hydridoacetylide and hydridovinylidene-osmium clusters with [(η-C5H5)Ni(CO)]2 and of (η-C5H5)2Ni2(HC2But) with osmium carbonyls. Synthesis and crystal structure of (η-C5H5)Ni(μ-H)Os3(CO)9(μ4-η2-CCHBut)
The heterometallic cluster (η-C5H5)Ni(μ-H)Os3(CO)9(CCHBut) has been obtained in low yield by treating hydridoacetylide- or hydridovinylidene-osmium clusters with [(C5H5)Ni(CO)]2 under hydrogen. The structure of this complex has been determined by X-ray methods.
