Two new molecular structures, namely 1,3-bis(trimethylsilyl)-1H-benzimidazole-2(3H)-thione, C13H22N2SSi2, (2), and 1-trimethylsilyl-1H-benzimidazole-2(3H)-thione, C10H14N2SSi, (3), are reported. Both systems were derived from 1H-benzimidazole-2(3H)-thione. Noncovalent C-H···π interactions between the centroid of the benzmidazole system and the SiMe3 groups form helicoidal arrangements in (2). Dimerization of (3) results in the formation of R2(2)(8) rings via N-H···S interactions, along with parallel π-π interactions between imidazole and benzene rings.
报道了两种新的分子结构，即1,3-双（三甲基硅基）-1H-苯并咪唑-2(3H)-硫酮，C₁₃H₂₂N₂SSi₂，（2），以及1-三甲基硅基-1H-苯并咪唑-2(3H)-硫酮，C₁₀H₁₄N₂SSi，（3）。这两种体系均由1H-苯并咪唑-2(3H)-硫酮衍生而来。在（2）中，苯并咪唑体系的质心与SiMe₃基团之间的非共价C-H···π相互作用形成螺旋排列。（3）的二聚化通过N-H···S相互作用导致形成R₂²(8)环，同时咪唑环和苯环之间存在平行的π-π相互作用。
