crystal structure of trans-[CoIII(3)Cl2]Cl·4H2O shows that the macrocycle adopts the trans-III conformation, in which the anthracene moiety is extended away from the cobalt ion and the anthracene to Co separation is 7.22 Å. For the related complex trans-[CoIII(2)Cl2]Cl·0.5CH3OH, however, the anthracene is bent over the highly conjugated tetracycle and significant interactions between the anthracene and the
这项工作报告了钴配合物反式-[Co III(2)Cl 2 ] Cl·0.5CH 3 OH和反式-[Co III(3)Cl 2 ] Cl·4H 2 O的合成,结构和一些光化学。,其中2是6-(蒽-9-基甲基)-1,4,8,11-四氮杂环十四烷-5,7-二酮而3是6-(蒽-9-基甲基)-1,4,8,11-四氮杂环十四烷。在编写大环配体,3,形成多环双(氨基)中间体及其随后的酸水解到3是比传统方法更清洁的方法,在传统方法中,类似的二氧环素2减少了硼烷试剂。反式[Co III(3)Cl 2 ] Cl·4H 2 O的晶体结构表明:大循环采用反式-III构象,其中蒽部分远离钴离子延伸,且蒽Co的分离度为7.22Å。对于相关的复合物反式-[Co III(2)Cl 2 ] Cl·0.5CH 3 OH,蒽 弯曲高度共轭的四环和之间的显着相互作用 蒽和复杂的发生。一种新的新的复合物,即降解产物反式[Co(12)Cl
