An incomplete cube-like aray of Cu, Zn, I with O atoms from 2-dimethylaminoethanol formed directly form zero-valent metal powders

摘要

The new heterotrinuclear complex [Cu_2Zn(NH_3)I_3(Me_2Ea)_3] was prepared for the first time from copper and zinc powders, ammonium iodide and 2-dimethylaminoethanol (HMe_2Ea) in methanol in air. X-ray crystallographic analysis reveals the asymmetric Cu_2ZnO_3I core with the structure that can be described as a distorted cube missing one corner.the #mu#-alkoxo- and #mu#-iodobridging between metal centres results in copper-copper and two copper-zinc separations being 3.353(2), 3.197(2) and 3.225(2) A, respectively.
