is stabilized by six dithiophosphate and four alkynyl ligands. Compound 2b is the first Ag(I) cluster containing a twelve-coordinated bromide. The structural features of all six clusters are highly similar, providing a comparison basis of the inverse coordination for halides. Besides, the detailed structural analysis illustrates how the inverse coordination of a halide has influenced the size of the
两个系列的超配位卤化物中心 M 12立方八面体簇,[M 12 (μ 12 -X)S 2 P(O n Pr) 2 } 6 C CPh} 4 ](PF 6 ), 1a–c和2a-c(其中 M = Cu, 1 ; Ag, 2 ; X = Cl, a ; Br, b ; I, c)合成并通过 ESI-MS、多核磁共振光谱、IR 和 UV-Vis 充分表征光谱学、光致发光分析和单晶 X 射线晶体学。结构1c、2b和2c显示了封装在 M 12笼中的十二配位卤化物,其由六个二硫代磷酸盐和四个炔基配体稳定。化合物2b是第一个包含十二配位溴化物的Ag( I ) 簇。六个簇的结构特征高度相似,为卤化物的逆配位提供了比较依据。此外,详细的结构分析说明了卤化物的逆配位如何影响立方八面体 M 12骨架的尺寸。
