Treatment of ortho-carborane, n-butyl lithium, sulfur, and (p-cymene)RuCl(2) in varying ratio led to four new compounds (p-cymene)Ru[S(3)(C(2)B(10)H(10))(2)] (3), (p-cymene)Ru(2)(μ(2)-S(2)C(2)B(10)H(9))(μ(3)-S(2)C(2)B(10)H(10)) (4), (p-cymene)RuRu(μ(2)-η(2):η(2)-S(2)) (μ(2)-η(2):η(1)-S(2)Cl)(μ(2)-S(2)C(2)B(10)H(10))(2) (5), and (p-cymene)RuRu(μ(2)-η(1):η(1)-S(2))(μ(3)-η(2):η(2)-S(4)) (μ(2)-S(2)C(2)B(10)H(10))(2) (6), respectively. In 3, the ruthenium atom is coordinated by three S atoms from a in situ generated tridentate S(3)(C(2)B(10)H(10))(2) ligand. 4 consists of two identical dinuclear (p-cymene)Ru(2)(μ(2)-S(2)C(2)B(10)H(9))(μ(3)-S(2)C(2)B(10)H(10)) subunits which connect to each other via the Ru-Ru bond and two bridging o-carborane-1,2-dithiolate ligands. In 4, a Ru-B bond is present. 5 contains a Ru(3)(μ(2)-S)(2)(μ(2)-S(2))(μ(2)-S(2)Cl) core, and the central ruthenium atom is coordinated by seven S atoms in a distorted pentagonal bipyramidal geometry. In 5, a S-Cl bond is generated. 6 has a novel Ru(3)(μ(2)-S)(2)(μ(2)-S(2))(μ(3)-S(4)) core, and the three ruthenium atoms are connected through the two terminal sulfur atoms of the S-S-S-S chain in a μ(3) binding fashion. All the four complexes have been characterized by elemental analysis, mass, NMR, and X-ray crystallography.
用不同比例的邻-碳硼烷、正丁基锂、硫和(p-枯烯)RuCl2处理得到了四个新化合物[(p-枯烯)Ru[S(3)(C2B10H10))(2)] (3)、[(p-枯烯)Ru2(μ2-μ2-S2C2B10H9)(μ3-μ2-S2C2B10H10))(2)] (4)、(p-枯烯)RuRu(μ2-η2:η2-S2)(μ2-η2:η1-S2Cl)(μ2-μ2-S2C2B10H10))(2)] (5)和(p-枯烯)RuRu(μ2-η1:η1-S2)(μ3-η2:η2-S4)(μ2-μ2-S2C2B10H10))(2)] (6)。在 3 中，钌原子由原位生成的三齿S(3)(C2B10H10))(2)配体的三个 S 原子配位。4 由两个相同的双核(p-枯烯)Ru2(μ2-μ2-S2C2B10H9)(μ3-μ2-S2C2B10H10)) 组成，通过 Ru-Ru 键和两个桥联邻-碳硼烷-1,2-二硫醇配体连接在一起。在 4 中，存在 Ru-B 键。5 包含一个 Ru(3)(μ2-S)(2)(μ2-S2)(μ2-S2Cl)核心，中心钌原子在扭曲的五重锥形几何形状中由七个 S 原子配位。在 5 中，生成一个 S-Cl 键。6 具有一个新颖的 Ru(3)(μ2-S)(2)(μ2-S2)(μ3-S4))核心，三个钌原子通过 S-S-S-S 链的两个末端硫原子以 μ3 键合方式连接。所有四个配合物均通过元素分析、质量、NMR 和 X 射线晶体学进行了表征。
