Reaction of CS2 with metal cluster carbonyls of the iron triad: synthesis and X-ray crystal structure of [Fe4(CO)12(C2S4)]
Abstract
Dodecacarbonyltri-iron, [Fe3(CO)12], reacts with an execess of CS2 in hexane at 80 °C under a CO–Ar atmosphere (1:1, pressure ca. 10 atm) to give a number of products in including, in low yield, [Fe4(CO)12(C2S4)] which, on the basis of a single-crystal X-ray analysis, has been shown to contain two Fe2(CO)6 units bridged by a C2S4 unit which may be regarded as a derivative of ethenetetrathiol.
