摘要：
Photolysis of the heterometallic complex (mu-H)Os-3{mu-O2CC5H4Mn(CO)(3)}(CO)(10) together with PPh3 results in replacement of the CO groups by PPh3 both at the Mn atom and in the Os-3 metallocycle to afford the complexes (mu-H)Os-3{mu-O2CC5H4Mn(CO)(2)PPh3}(CO)(10), (mu-H)Os-3{mu-O2CC5H4Mn(CO)(3)}(CO)(9)PPh3, and (mu-H)Os-3{mu-O2CC5H4Mn(CO)(2)PPh3}(CO)(9)PPh3 (two isomers). The reaction is also accompanied by the partial removal of the Mn(CO)(3) group followed by the protonation of the cyclopentadienyl group and formation of triosmium clusters (mu-H)Os-3(mu-O2CC5H4R)(CO)(10) (R = H, Et).
