In the title co-crystal, CHN ·CHOS·CHN, the two 1,2-di-methyl-imidazole rings exist as partially protonated moieties in the asymmetric unit as a two-part disordered unit wherein the acidic hydrogen atom is bound to each ring. The two imidazolium cations share a strong hydrogen bond the acidic hydrogen atom, which is disordered between two positions, being bonded to the first second imidazole ring in a 0.33 (2) to 0.67 (2) ratio. A benzene sulfonate anion is present for charge balance and inter-acts with the aromatic H atoms on both imidazole rings as well as with the methyl groups on the rings.
在标题共晶体CHN·CHOS·CHN中，两个1,2 - 二甲基咪唑环在不对称单元中以部分质子化部分的形式存在，为一个两部分无序单元，其中酸性氢原子与每个环相连。两个咪唑鎓阳离子共享一个强氢键，酸性氢原子在两个位置之间无序分布，以0.33 (2) 至0.67 (2) 的比例与第一个和第二个咪唑环相连。存在一个苯磺酸盐阴离子用于电荷平衡，并与两个咪唑环上的芳香氢原子以及环上的甲基相互作用。
