以一个新的面内配体（3S，4S）-3，4-己二胺（hxn）.2为原料，合成了一种新型的溴桥钯链配合物[Pd（hxn）2Br]（TsO）2（2）（TsO-=对甲苯磺酸盐），通过单晶X射线结构分析和偏振拉曼光谱证实了该配合物的结构为PdII/PdIV混合价态. hxn配体在配体的甲基和TsO-阴离子的O原子之间提供了额外的氢键（CH···O），这比在具有羟基的链状配合物[Pd（dabdOH）2Br] Br 2（1）中观察到的弱。
A novel Br‐bridged Pd chain complex, [Pd(hxn)2Br](TsO)2(2) (TsO–=p‐toluenesulfonate), was synthesized from a new in‐plane ligand (3S,4S)‐3,4‐diaminohexane (hxn).2forms PdII/PdIVmixed‐valence state, as confirmed by single‐crystal X‐ray structure analysis and polarized Raman spectra. The hxn ligand provides the additional hydrogen bonds (CH···O) between the methyl group of the ligands and the O atoms of TsO–anions, which are weaker than those observed in the chain complex with hydroxy group, [Pd(dabdOH)2Br]Br2(1).
