摘要:
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 1(4), namely, {[Au-4(-dppm)(2)(-dctp(2-))](BF4)(2)}(4)(CH3CN)(2) (dppm=bis(diphenylphosphino)methane, dctp(2-)=N,N-bis(dicarbodithioate)-2,11-diaza[3.3]paracyclophane) is reported. The complex has been characterized by single-crystal X-ray diffraction analysis, (HNMR)-H-1 spectroscopy, (CNMR)-C-13 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)angstrom generated by (AuAuI)-Au-I attractions. UV/visible and luminescence spectroscopy revealed that this (AuAuI)-Au-I bonded metallo-macrocycle exhibited yellow phosphorescence.
