iodide bridged copper(I) complexes [Cu2(µ‐I)2(mes‐BIAN‐5‐NO2)2], 3 and [Cu2(µ‐I)2(mes‐BIAN‐4‐NO2)2], 4 , were obtained in good yields by treatment with an equimolar amount of CuI. All compounds were characterized by elemental analysis, single‐crystal X‐ray diffraction, 1H‐NMR, 13C‐NMR, FTIR, UV/Vis spectroscopy. DFT calculations helped to understand the different molecular structure observed in the
