Abstract: | Metal–metal bonding interactions have been employed as an efficient strategy to generate a number of unique gold(I) metallo‐macrocycles with fascinating functions. The self‐assembly, crystal structure and emission property of novel nest‐like tetramer 14 , namely, {[Au4(μ‐dppm)2(μ‐dctp2?)](BF4)2}4 ? (CH3CN)2 (dppm=bis(diphenylphosphino)methane, dctp2?=N,N′‐bis(dicarbodithioate)‐2,11‐diaza[3.3]paracyclophane) is reported. The complex has been characterized by single‐crystal X‐ray diffraction analysis, 1H NMR spectroscopy, 13C NMR spectroscopy, and CSI‐MS spectrometry. The aggregate demonstrates the sixteen gold(I) atoms are arranged in a ring with a circumference of 50.011(68) Å generated by AuI???AuI attractions. UV/visible and luminescence spectroscopy revealed that this AuI???AuI bonded metallo‐macrocycle exhibited yellow phosphorescence. |
