Abstract

A novel set of stereochemically nonrigid monomeric two-coordinate copper(I) complexes, [Cu(η1-H2CPz″2)2]ClO41, [Cu(HPz″)2]ClO42, and [Cu(HPz″)(η1-H2CPz″2)]ClO43, where Pz″ = 3,5-di-tert-butylpyrazolyl, has been synthesized and characterized by X-ray diffraction and variable-temperature 1H NMR spectroscopy. Based on the 1H 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 H2CPz″2 ligands can proceed simultaneously on a single copper(I) ion.
