novel, neutral, heteroleptic copper(I)-complexes, incorporating 4H-imidazolates as well as the phosphane ligands XantPhos and DPEPhos is reported. The complexes were characterized in the solid state as well as in solution by means of single crystal X-ray diffraction as well as NMR spectroscopy, mass spectrometry and elemental analysis. The copper(I)-4H-imidazolate complexes show a broad intense absorption
