Abstract
The reaction of CuI with dialkylcyanamides yielded copper(I) cluster complexes [Cu4I4(NCNR2)4] (R2 = Me2, Et2, C4H8, C5H10, C4H8O), as well as coordination polymer catena-[CuI(NCNMe2)]n. The structures of the obtained compounds were determined by single-crystal X-ray diffraction analysis, atomic emission spectroscopy (Cu), CHN elemental analysis, X-ray phase analysis, and IR spectroscopy. The prepared clusters luminesce at room temperature in the solid state with an emission maximum in the range of 554–600 nm upon irradiation at 365 nm.
