Three isomorphous compounds have been prepared, i.e. [Cu^I(PPh₃)₂(Hnor)I], [Cu^I(PPh₃)₂(Hnor)Cl] and [Cu^I(PPh₃)₂(Hnor)Br]. The compounds are tetrahedrally coordinated, as deduced from the single-crystal X-ray diffraction analysis of the iodide compound. The chloride and bromide compounds were found to be isomorphous. Significant twinning hampered a detailed X-ray diffraction study of the bromide derivative. All three compounds are highly luminescent in the solid state at room temperature and at 100 K. In addition, in acetonitrile (solution) at room temperature the compounds are luminescent.
