Notes:
Formation of strongly colored complexes of Cu+ with glyoxal-bis-(N-t-butylimin) (GLI) is observed in acetonitrile. Optical measurements reveal two complexes, Cu(GLI)+ (ṽmax = 26.0 kK, δ = 2800) and Cu(GLI)2+ (ṽmax = 19.3 kK, ε = 8530). The equilibrium constants (0.1M tetraethylammoniumperchlorate) are logK1 = 3.9 and logK2 = 2.5. The equilibrium data are confirmed by potentiometric measurements with a copper electrode. In O-donor solvents, only the 1:2 complex is observed. Cu(GLI)2CIO4 can be crystallized as a dark red solid which is stable towards atmospheric oxygen.
