trimer assembly driven by halogen bonding interactions. Then, compounds 6 [Sn(5-bromoiso-phthalate)2(A2B2-P)·(PhNO2)], 7 [Sn(5-bromo-isophthalate)2(A2B2-P)·(DMF)], 8 [Sn(5-hydroxyisophthalate)2(A2B2-P)], and 9 [Sn(2,5-thiophene-dicarboxylate)2(A2B2-P)·(PhNO2)3] reveal strong halogen interactions alongside tight hydrogen bonding contacts. In 9 the relatively rare I···S halogen bonding has been detected in
这项工作报告了一种新的基于卟啉的超分子结构的设计结构,该结构借助卤素键以及卤素和氢键相互作用的组合而组装。为此,使用了锡IV(L)2-四芳基卟啉构建单元(L =轴向配体),其中,这些键的合适供体和受体功能已经以互补的方式引入了轴向配体和卟啉外围。我们在这种情况下揭示涉及不同取代的金属卟啉实体的八个结构:5,10,15,20-四(4'-碘苯基)卟啉(A 4 -P),5,10,15,20-四(4'-吡啶基)卟啉(B 4 -P),5-(4'-吡啶基)-10,15,20-三(4'-碘苯基)卟啉(A 3BP)和5,15-双(4'-吡啶基)-10,20-双(4'-碘苯基)卟啉(A 2 B 2 -P)以及连接到锡中心并具有分子识别作用的各种轴向配体容量。后者包括3-羟基吡啶(L1),羟基(L2),1-羟基苯并三唑(L3),5-溴吡啶-3-羧酸(L4),5-溴间苯二甲酸(L5),5-羟基间苯二甲酸(L6)
