摘要：

The new [Pt-13(CO)(12){Cd-5(mu-Br)(5)Br-2(dmf)(3)}(2)](2-) and [Pt-19(CO)(17){Cd-5(mu-Br)(5)Br-3(Me2CO2)}{Cd-5(mu-Br)(5)Br(Me2CO)(4)}](2-) clusters have been obtained in good yields by reaction of [Pt-12(CO)(24)](2-) with CdBr2 center dot H2O in dmf at 90 degrees C and structurally characterized by X-ray diffraction. Their structures consist of a Pt-centered Pt-13(CO)(12) icosahedron and a Pt-19(CO)(17) interpenetrated double icosahedron, respectively, decorated by two Cd-5(mu-Br)(5)Br5-x(solvent)(x) rings. Their surface decoration may be related to that of Au-Fe-CO clusters as well as to the staple motifs stabilizing gold-thiolates nanoclusters. An oversimplified and unifying approach to interpret their electron count is suggested.
