Copper complexes arsine ligands

Copper(I) nitrate complexes with organophosphines, arsines, and stibines can be readily prepared in good yield in alcohol solution by such ligand reduction reactions.9 In the cases of the arsines and stibines, addition of copper powder... 

Silver iodide derivatives of trialkyl-phosphines and -arsines were prepared in 1937 for comparison with their copper(I) iodide analogues.201 The preparations involved shaking the ligands with silver iodide dissolved in concentrated aqueous KI. The products were found to be tetramers and of similar structure to the Cu1 complexes. The Pr As silver complex was isomorphous with [Cul-AsEt3]4. Molecular weight determinations in a range of organic solvents showed that partial dissociation occurred in solution. 

In phosphine and arsine complexes of the type LM(diketonate) (M = Ag, Au) and CuL2(dike-tonate), t]2 oxygen bonded diketonate ligands occur in the copper(I) and silver(I) derivatives but the gold(I) analogues feature the jj, carbon bonded form.483... 

Numerous complexes of Au1 with substituted phosphine, arsine and sulfide ligands as well as carbon monoxide can be obtained. Unlike the copper(i) and silver(i) complexes, which are polymeric with four-coordinated metal...
