Tetra-, di-, and mononuclear copper(I) complexes containing (S,S)-iPr-pybox and (R,R)-Ph-pybox ligands

Tetranuclear Cu4I4{(S,S)-iPr-pybox}2] (1) and dinuclear Cu2Cl-{(S,S)-iPr-pybox}2]CuCl2] (2) copper(I) complexes have been synthesized by reaction of iPr-pybox with CuI and CuCl, respectively. Furthermore, dinuclear Cu2(R-pybox)2]PF6]2 R-pybox = (R,R)-Ph-pybox (3), (S,S)-iPr-pybox (4)] and mononuclear complexes Cu(R-pybox)2]PF6] R-pybox = (R,R)-Ph-pybox (5), (S,S)-iPr-pybox (6)] have been prepared by reaction of Cu(MeCN)4]PF6] and the corresponding pybox. The structures of complexes 1-3 have been determined by X-ray diffraction analyses.
