The synthesis of five new dihalogen/interhalogen charge transfer adducts featuring cyano and nitro functionalized 1,3-dithiole-2-thiones have been prepared and characterized by x-ray crystallography. The structures feature a complex series of intermolecular close contacts between heteroatoms, as well as hydrogen bonding, to give highly ordered, polymeric assemblies. The adduct 4.IBr crystallizes in
合成了五种新的二卤/卤间电荷转移加合物,其特征是氰基和硝基官能化的 1,3-二硫醇-2-硫酮,并通过 X 射线晶体学表征。该结构具有杂原子之间一系列复杂的分子间紧密接触以及氢键,以提供高度有序的聚合物组装。加合物 4.IBr 在非中心对称手性空间群中结晶,并具有通过氢键组装的分子堆栈。所有加合物的官能团都参与密切接触的网络,但不影响二卤素/卤素间物种的配位环境。
