The preparation, crystal structure and properties of a mixed-ligand copper(I) complex [CuI(PPh3)(DPPZ)].DMF

Abstract The mixed ligand mononuclear copper(I) complex of formula [CuI(PPh 3 )(DPPZ)]·DMF (DPPZ=dipyrido[3,2,-a:2′,3′-c]phenazine) has been synthesized and has been characterized by single-crystal X-ray diffraction method, FT-IR spectrum, the electrospray ionization mass spectrum and the thermogravimetric analysis. The pairwise π–π stacking between DPPZ ligands exists through the crystal lattice.
