Mono- and di-selenium complexes of chromium. Syntheses and crystal structures of (η5-C5H5)2Cr2(CO)4Se and (η5-C5H5)2Cr2(CO)4Se2
Abstract
The reaction of dicyclopentadienylhexacarbonyldichromium with elemental selenium at ambient temperature provides a simple route to (η5-C5H5)2Cr2(CO)4Se (1) and (η5-C5H5)2Cr2(CO)4Se22 in high yields.
