The first stereochemically nonrigid monomeric two-coordinate copper(I) complexes with homoleptic and heteroleptic "N2" donor set.
A novel set of stereochemically nonrigid monomeric two-coordinate copper(I) complexes, [Cu(eta(1)-H(2)CPz''(2))(2)]ClO(4) 1, [Cu(HPz'')(2)]ClO(4) 2, and [Cu(HPz'')(eta(1)-H(2)CPz''(2))]ClO(4) 3, where Pz'' = 3,5-di-tert-butylpyrazolyl, has been synthesized and characterized by X-ray diffraction and variable-temperature (1)H NMR spectroscopy. Based on the (1)H NMR line shape analysis of complexes 1 and 2, the intramolecular fluxional process was proposed for these two-coordinate copper(I) complexes. Also, the mixed ligand complex 3 shows that these two different dynamic binding modes of the coordinated HPz'' and H(2)CPz''(2) ligands can proceed simultaneously on a single copper(I) ion.
