[Os3(CO)12Cl(SnCl2){cpM(CO)3}]: heteropentametallic chain cluster complexes with no bridging ligands (cp =η5-cyclopentadienyl; M = Mo or W)
Abstract
The title compounds have been prepared in high yields by the reactions of Na[cpM(CO)3] with [Os3(CO)12Cl(SnCl3)](cp =η5-C5H5) and the tungsten compound has been shown, by X-ray crystallography, to contain a pentametallic chain held together only by metal–metal bonds.
