dinuclear copper(I) complexes 1 and 2 were prepared by reacting PNP ligands ArN(PPh2)2, (Ar = 2,6‐Me2C6H3; L1) with CuCl and CuBr. By altering the position of the methyl substituents from ortho to meta (Ar = 3,5‐Me2C6H3; L2), trinuclear copper(I) complexes 3 and 4 were obtained, while the methyl substituent at the para position (Ar = 4‐MeC6H4; L3) led to the tetranuclear copper(I) complexes 5 and 6.
双核铜(I)配合物1和2是通过PNP配体ArN(PPh 2)2(Ar = 2,6-Me 2 C 6 H 3 ; L1)与CuCl和CuBr反应制备的。通过将甲基取代基的位置从邻位改变为间位(Ar = 3,5-Me 2 C 6 H 3 ; L2),可以获得三核铜(I)配合物3和4,而甲基取代基位于对位( Ar = 4-MeC 6 H 4;L3)导致四核铜(I)配合物5和6。单晶X-射线研究表明不同的Cu ...在铜配合物相互作用1 - 6范围从2.650至2.935埃。发现铜(I)配合物3 – 6表现出机械变色和热致变色的发光行为,这可能是由于它们的Cu ··· Cu距离减小所致。
