similar fashion in the absence of metal ions, a new 1,10-phenanthroline (phen)-based extended ligand, C12H6N2[CHNC6H4NH(C10H6N)]2 (L1), its copper(I) complexes, [Cu2(C12H6N2CHNC6H4NH(C10H6N)}2)2] [PF6]2 (1), [Cu2(C12H6N2CHNC6H4NH(C10H6N)}2)2][BF4]2 (2), [Cu2(C12H6N2CHNC6H4NH(C10H6N)}2)2][CuCl2]2·CH2Cl2 (3), and [Cu4(C12H6N2CHNC6H4NH(C10H6N)}2)2][Cu2I4] (4), were prepared and structurally characterized
为了分析超分子相互作用对螺旋结构的贡献,并研究在没有金属离子的情况下,配体折叠是否可以仅由质子以类似的方式诱导,一种新的基于 1,10-菲咯啉 (phen) 的扩展配体 C12H6N2[ CHNC6H4NH(C10H6N)]2(L1),其铜(I)络合物,[Cu2(C12H6N2CHNC6H4NH(C10H6N)}2)2][PF6]2(1),[Cu2(C12H6N2CHNC6H4NH(C10H6N)}2 )2][BF4]2 (2)、[Cu2(C12H6N2CHNC6H4NH(C10H6N)}2)2][CuCl2]2·CH2Cl2 (3)、[Cu4(C12H6N2CHNC6H4NH(C10H6N)}2)2] [Cu2I4] (4) 被制备和结构表征。根据阴离子的性质,配体 L1 以两种有趣的不同方式包裹铜 (I) 离子。虽然二铜螺旋体 1-3 和四铜螺旋体 4 显示出显着的分子间相互作用,显示出与
