The asymmetric unit of the title compound, (C(13)H(15)N(2)S(2))[RuCl(3)(C(10)H(14))], contains a 1,3-(2-thienylmeth-yl)-4,5-dihydro-imidazolium cation and a trichlorido(η(6)-p-cymene)ruthenate(II) anion. The thio-phene rings of the cation are disordered by an 180° rotation about the thio-phene-CH(2) bonds with occupancies of 0.847 (5)/0.153 (5) and 0.700 (5)/0.300 (5), respectively. The Ru atom exhibits a distorted octa-hedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three Cl atoms occupying the other three sites. The short C-N bond lengths in the imidazoline ring indicate partial electron delocalization within the N-C-N fragment. Cation and anions are connected through five inter-molecular C-H⋯Cl hydrogen bonds and one C-H⋯π hydrogen bond, forming a three-dimensional hydrogen-bonded network.
标题化合物（C₁₃H₁₅N₂S₂）[RuCl₃（C₁₀H₁₄）]的不对称单元包含一个1,3 -（2 - 噻吩甲基）- 4,5 - 二氢咪唑鎓阳离子和一个三氯（η⁶ - 对异丙基苯）钌（II）阴离子。阳离子的噻吩环通过围绕噻吩 - CH₂键的180°旋转而无序，占有率分别为0.847（5）/0.153（5）和0.700（5）/0.300（5）。Ru原子呈现出扭曲的八面体配位，对异丙基苯配体的苯环形式上占据三个位置，三个Cl原子占据另外三个位置。咪唑啉环中较短的C - N键长表明N - C - N片段内存在部分电子离域。阳离子和阴离子通过五个分子间C - H⋯Cl氢键和一个C - H⋯π氢键相连，形成三维氢键网络。
