In the crystal structure of the title compound, [Ag(3)Cl(C(8)H(15)N(3))(6)]Cl(2), the Ag(I) ion, which is located on a twofold rotation axis, exists in a T-shape coordination environment. Two carbene C atoms of the N-heterocyclic carbene (NHC) ligands are bonded tightly forming a slightly bent Ag(NHC)(2) cation [C-Ag-C angle = 162.80 (18)°]. Three of these complex cations are further aggregated by one bridging chloride anion, which is lying on a threefold rotoinversion axis and is only loosely binding to the Ag(+) ions. The N atom of the amine group is not engaged in any coordinative bond.
在标题化合物[Ag₃Cl(C₈H₁₅N₃)₆]Cl₂的晶体结构中,位于二重旋转轴上的Ag(I)离子存在于T形配位环境中。N-杂环卡宾(NHC)配体的两个卡宾C原子紧密键合,形成一个略微弯曲的[Ag(NHC)₂]⁺阳离子[C-Ag-C角 = 162.80 (18)°]。三个这样的络合阳离子通过一个桥连氯离子进一步聚集,该氯离子位于三重旋转反演轴上,仅与Ag⁺离子松散结合。胺基的N原子不参与任何配位键。
