摘要：

Stirring at room temperature of [(CO)(6)Fe-2{mu-SeC(H)=C(CH2OH)Se}] with Pt(PPh3)(4) or Pt(C2H4)(PPh3)(2) in dichloromethane affords the mu(3)-Se-bridged mixed-metal cluster pentacarbonyl-1 kappa(3)C,2 kappa C,3 kappa C-mu(3)-selenido-1:2:3 kappa(3)Se-bis(triphenylphosphine)-2 kappa P,3 kappa P-irondiplatinum (2 Fe-Pt), [FePt2(mu(3)-Se)(C18H15P)(2)(CO)(5)]. The structure can be described as an FePt2Se butterfly; each Pt atom is coordinated by one CO and one PPh3 group, whereas the Fe atom is bonded to three CO groups. The Fe atom is in a distorted octahedral environment. The bridging Se atom is bonded to the open triangular array of FePt2 in a mu(3) coordination mode. The geometry around the Pt atoms is distorted square planar.
