Abstract

Two novel complexes, (p-cymene)Ru(E₂C₂B₁₀H₉)(Ph₂C(OH)CCH₂), designated as I (E = S) and II (E = Se), are successfully synthesized and characterized using NMR, IR, MS, and elemental analysis techniques. X-ray structural analysis is performed on complex I, which crystallizes in monoclinic system, space group P2₁/c with a = 11.6648(12) Å, b = 16.9404(17) Å, c = 15.6876(17) Å, β = 101.7490(10), C₂₇H₃₆B₁₀ORuS₂, M_r = 649.85, V = 3035.0(5) Å³, D_c = 1.422 g/cm³, Z = 4, F(000) = 1328, µ(MoK_α) = 0.677 mm^–1, R = 0.0505 and ωR = 0.0793 for 3206 observed reflections (I > 2σ(I)). Structural analysis indicates the coordination of C=C bonds, formation of C–S bonds, and B-substitution at B3 within the o-carborane cage, resulting in the formation of a Ru–B bond. Furthermore, the ruthenium atom coordinated to p-cymene complies with the 18-electron rule.

1,1-二苯基-2-丙基-1-醇和邻碳硼烷二氯基配体组装钌配合物的合成与表征

成功合成了两个新型配合物（p-花枝烃）Ru(E2C2B10H9)(Ph2C(OH)CCH2)，编号为I （E = S）和II (E = Se)，并利用核磁共振、红外、质谱和元素分析技术对其进行了表征。对单斜晶系的配合物I进行x射线结构分析，空间群P21/c， a = 11.6648（12） Å， b = 16.9404（17） Å， c = 15.6876（17） Å， β = 101.7490(10), C27H36B10ORuS2, Mr = 649.85, V = 3035.0(5) Å3, Dc = 1.422 g/cm3, Z = 4， F(000) = 1328，µ(MoKα) = 0.677 mm-1, R = 0.0505, ωR = 0.0793 （I > 2σ(I)）结构分析表明，C=C键配位，C -s键形成，o-碳硼烷笼内B3处b取代，形成Ru-B键。此外，钌原子与对花香烃配位符合18电子规则。
