Abstract
Thermal stability of [ClSb{Cr(CO)5}2]2 and its reaction with pyridine was studied by static tensimetry method with membrane null-manometer. [ClSb{Cr(CO)5}2]2 is thermally unstable and decomposes at 50–80°C with the formation of carbon monooxide and chromium hexacarbonyl. Upon reaction with pyridine on heating instead of the expected ClSb{Cr(CO)5}2∙Py formation of СO, Cr(CO)6, Cr(CO)5∙Py, antimony and supposedly complex of chromium dichloride with pyridine are formed.
