A new ruthenium complex, [RuBrCl(C(28)H(32)N(2))], has been synthesized and characterized by elemental analysis, (1)H NMR, (13)C NMR, IR-spectroscopy and a single-crystal X-ray diffraction study. The Ru atom in this complex is best described as having a considerably distorted octa-hedral coordination environment with the arene occupying three coordination sites. Two further coordination sites are occupied by chloride and bromide ligands, while the sixth site is occupied by the carbene. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C(6)H(4)C(CH(3))(3) arene by a CH(2) bridge. This leads to a system with very little apparent strain. The two halogen atoms are disordered between Br and Cl. Two partial Cl atoms share the same sites as two partial Br atoms so that the title compound effectively has one Cl and one Br atom. C-H⋯X (X = Cl, Br) hydrogen bonds help to stabilize the crystal structure.
一种新型钌配合物[RuBrCl(C₂₈H₃₂N₂)]已被合成，并通过元素分析、¹H NMR、¹³C NMR、红外光谱和单晶X射线衍射研究进行了表征。该配合物中的Ru原子最好描述为具有严重扭曲的八面体配位环境，其中芳烃占据三个配位点。另外两个配位点被氯和溴配体占据，而第六个位点被卡宾占据。配体的卡宾部分是一个苯并咪唑环。该环通过一个CH₂桥与C₆H₄C(CH₃)₃芳烃相连。这导致了一个几乎没有明显应变的体系。两个卤素原子在Br和Cl之间无序排列。两个部分Cl原子与两个部分Br原子占据相同的位点，因此标题化合物实际上有一个Cl原子和一个Br原子。C-H⋯X（X = Cl，Br）氢键有助于稳定晶体结构。
