Two‐Dimensional Triangular and Square Heterometallic Clusters: Influence of the Closed‐Shell d 10 Electronic Configuration

Gilded rafts : Oligomeric 2D raft clusters {M[m]} n (M=Cu, n =3; M=Ag or Au, n =4; see picture) with the same bridging metalloligand [m]={CpMo(CO) 3 } were prepared and structurally characterized. The ν 2 ‐triangular (M=Cu) or ν 2 ‐square (M=Ag, Au) structures of their metal–metal‐bonded cores allow comparative evaluation of the d 10 ⋅⋅⋅d 10 interactions, and theoretical calculations point to a favorable contribution of diagonal Au⋅⋅⋅Au or Ag⋅⋅⋅Ag interactions.
