In this note an exchange procedure of the acidic protons of H-ZSM5 by Cu(I) ions through reaction with CuCl in the gas phase is described. In the so obtained Cu(I)-ZSM5 exchanged zeolite the Cu(I) ions are in well defined configuration and form with NO mono and di-nitrosyl complexes of high structural and spectroscopic quality. The Cu(I)(NO)2 species are transformed at RT into Cu(II)(NO)X (X = O- and/or NO2-) species which could represent an intermediate in NO decomposition.

Abstract
In this note an exchange procedure of the acidic protons of H-ZSM5 by Cu(I) ions through reaction with CuCl in the gas phase is described. In the so obtained Cu(I)-ZSM5 exchanged zeolite the Cu(I) ions are in well defined configuration and form with NO mono and di-nitrosyl complexes of high structural and spectroscopic quality. The Cu(I)(NO)2 species are transformed at RT into Cu(II)(NO)X (X = O- and/or NO2-) species which could represent an intermediate in NO decomposition.
