文摘
The doubly and quadruply bridged isomers [Mo2Cp2Cl2(渭-SMe)2] (4) and [Mo2Cp2(渭-Cl)2(渭-SMe)2] (3) have been obtained as side-products when the dicarbonyl precursor [Mo2Cp2(CO)2(渭-SMe)3]Cl (1) is warmed in toluene solution, the main product being the tris-thiolato-bridged compound [Mo2Cp2(渭-Cl)(渭-SMe)3] (2). Complex 4 is stable at room temperature but can be transformed into 3 at elevated temperatures. 3 and 4 have been crystallographically characterized, and both contain equivalent molybdenum centers. The Mo鈭扢o separations of 2.5909(11) and 2.4507(2) 脜 in 3(syn) and 4 are consistent with single and triple Mo鈭扢o bonds, respectively.
