What information about the identities of the samples purporting to be Cu(I) and Ag(I) aryl complexes could have been obtained by EXAFS and by mass spectrometry and by NMR  

There has been a lot of interest recently in complexes in which two different metal atoms are bonded to one another. The a basicity of electron-rich transition metals plays an important role, because late transition-metal ions, particularly when coordinated to electron-rich ligands such as phosphines, can act themselves as a donors, i,e. they act as Lewis bases and coordinate to electron-deficient atoms. A simple example of this is the complex [(L)(Cy3P)Pt — AICI3] (L = cyc/o-[CHN( Bu)]2C ) [100]. 

Here we discuss two complexes involving palladium and tin. They have been prepared according to the following equation
