Metal carbonyl photochemistry. Part 2. Photochemistry of hexacarbonyls in glasses containing oxygen donors; the species [M(CO)5(mthf)](M = Cr, Mo, W, or V–I), cis-[M(CO)4(mthf)2], and fac-[M(CO)3(mthf)3](M = Cr, Mo, or W)

Abstract

The title species have been prepared by photolysis of [M(CO)₆] in mthf glass at 77 K, and (for M = Mo or W) in doped hydrocarbon glasses {in which there is evidence for photoconversion of Mo(CO)₅ into [Mo(CO)₅(mthf)]}. The compounds [Mo(CO)₅(CH₃COCH₃)], [Mo(CO)₅(OCHCH₃)], and [Mo(CO)₅(HOR)] have also been characterised at low temperature.
