disruption of the characteristic columnar packing mode of the CTV, a result of the presence of the metal center, leads to the inclusion of neutral and anionic guest species (NO2Me, Et2O, HCF3CO2}2-, etc.) within the CTV cavity. For complexes where n = 2 or 3 the inclusion of anionic guests is invariably observed. The extent of anion binding has been established by means of X-ray crystal structure determinations
用银盐 AgX (M = Ru, L = 4-MeC6H4CHMe2, C6H6, 或 C6Me6; M = Ir, L = C5Me5) 处理氯化物桥接物质 [M(L)Cl(μ-Cl)}2] (M = Ru, L = 4-MeC6H4CHMe2, C6H6, or C6Me6; M = Ir, L = C5Me5) X = BF4、CF3SO3、CF3CO2 等),然后与碗状大环环三戊四烯 (CTV) 回流,导致单、二和三金属 CTV 配合物的清洁形成 [M(L)}n(CTV) ]X2n (n = 1, 2, 3)。可以通过阴离子复分解生成其他盐(X = ReO4-,I-)。所有三种类型的复杂都显示出新颖的主客体特性。在单金属主体的情况下,由于金属中心的存在,CTV 的特征柱状填充模式被破坏,导致包含中性和阴离子客体物种(NO2Me、Et2O、HCF3CO2}2-等)在 CTV 腔内。对于
