A tetrameric copper(I) alkoxide with a pi-tethered ligand: 2-allyl-6-methylphenoxocopper(I)
Artikel i vetenskaplig tidskrift, 2002

The complex 2-allyl-6-methylphenoxocopper(I) has been prepared by reaction between mesitylcopper(I) and 2-allyl-6-methylphenol. Crystallographic studies show that the compound is tetrameric with a distorted cubane-type copper(I)-oxygen core, and with additional pi-coordination of the ligand to copper through the alkene functionality (nu(C=C)=1520 cm(-1)). The ligands thus act both as chelates and as bridges between adjacent copper(l) centres. Copper(l) exhibits trigonal pyramidal coordination geometry with Cu-C distances to the C=C group of 1.976(9) and 2.017(11) Angstrom and Cu-O distances of 1.973(6), 2.021(6) and 2.577(6) Angstrom, respectively.
