Ion pairs of -(2,6-dimethylphenyl)-substituted triazatriangulenium (TATA) cation with various counteranions were synthesized to investigate the interactions for the bulky cation. Single-crystal X-ray analysis of the TATA ion pairs revealed solid-state ion-pairing assemblies without stacking at the cationic π-planes. The TATA cation showed counteranion-dependent assembly structures, with smaller counteranions located at the top of TATA and bulkier counteranions displaced from the TATA plane to interact with the surrounding TATA.
合成了 -(2,6-二甲基苯基) 取代的三氮杂三角烯鎓 (TATA) 阳离子与各种抗衡阴离子的离子对，以研究这种体积较大的阳离子之间的相互作用。对 TATA 离子对进行的单晶 X 射线分析表明，在阳离子的 π 平面上不存在堆积的固态离子对组装结构。TATA 阳离子呈现出依赖于抗衡阴离子的组装结构，较小的抗衡阴离子位于 TATA 的顶部，而体积较大的抗衡阴离子则从 TATA 平面位移，以便与周围的 TATA 相互作用。
