New coinage metal-coordinated intermetalloid E-10 clusters (R3P)AuGe9(Hyp)(3)Pt(PPh3) (R = Bu, Et)

摘要

We present the synthesis and characterization of the intermetalloid clusters R3PAuGe9(Hyp)(3)Pt(PPh3) [R = Et, Bu; Hyp = Si(SiMe3)(3)] obtained by the reaction of R3PAuGe9(Hyp)(3)(R = Et, Bu) with Pt(PPh3)(4). The realized cluster enlargement is also known for the neutral cluster Ge-9(Et)(Hyp)(3), leading, however, to a different arrangement of substituents and different dynamics in the solution.
