Reactions of 2,2'-pyridil (pyCOCOpy) with CuCl22H2O and CuBr2 in EtOH yielded the mononuclear complex [Cu(pyCOOEt)2Cl2]H2O (1) and the one-dimensional, mixed-valence complex [Cu2ICuII(pyCOOEt)2Br4]n (2), respectively. Both complexes crystallize in the triclinic space group P 1¯. The lattice constants are a=8.382(2), b=9.778(2), c=7.814(2), α=101.17(1), β=114.55(1), γ=94.14(1) for 1 and a=8.738(1), b=9.375(2), c=7.966(1), α=79.09(1), β=64.25(1), γ=81.78(1) for 2. 2,2'-pyridil undergoes a metal-assisted alcoholysis and oxidation leading to decomposition and yielding the ethyl picolinate (pyCOOEt) ligand. The autoredox process associated with the reduction of copper(II) to copper(I) in the case of complex 2 is discussed in terms of the increased redox activity of the copper(II) bromide system relative to the copper(II) chloride system.
