Organometallic polyphosphorus and -arsenic ligands as linkers between pre-assembled linear CuI fragments

Zusammenfassung

A simple and straightforward synthesis of a new linear trinuclear Cu-I cluster with polyphosphine ligands is presented. The reaction of this pre-organized Cu-3 precursor with En ligand complexes (E = P, As; n = 2, 5) affords discrete complexes exhibiting end-on eta(1)-coordination of the E-2 ligands or one-dimensional coordination polymers featuring sigma-1,3-bridging E-5 rings, respectively.
