The synthesis and X-ray structure analysis of the dianion [Ru18(C)2(CO)42Hg3]2–, the first octadecaruthenium cluster
Abstract
The heterometallic dianion [Ru18Hg3(C)2(CO)42]2– has been obtained from the decanuclear ruthenium carbido-dianion [Ru10C(CO)24]2– as its [N(PPh3)2]+ salt by reaction with mercury(II) trifluoroacetate, and has been shown by X-ray single crystal analysis to be a dimer of two tricapped octahedral Ru9 cluster fragments, linked by a bridging Hg3 triangular unit.
