[Ru6(μ6-Sb)(CO)18]3-: deeply reduced metal carbonyl cluster embedded with naked μ6-Sb
{{output}}
The redox reaction of K3Sb and Ru3(CO)12 in the ethylenediamine (en) of 2,2,2-cryptand produces the deeply reduced [Ru6(μ6-Sb)(μ2-CO)2(CO)16]3- (1), wherein the unprecedented boat-like Ru6 cluster unit is embedded with μ6-Sb for the first time. The structur... ...
