Two novel one-dimensional (1D) coordination polymers of stoichiometry [Si(CH2SR)4}HgBr2]n (R = Me, 2a; R = Ph, 2b) have been prepared by treatment of HgBr2 with the functionalized silanes Si(CH2SR)4 (R = Me, 1a; R = Ph, 1b) acting as tetradentate thioether ligands. The extended structures result from intermolecular Hg–S interactions linking the monomeric Si(CH2SR)4}HgBr2 units, as established for
摘要 通过用功能化硅烷 Si(Si(CH2SR)4}HgBr2]n (R = Me, 2a; R = Ph, 2b) 处理 HgBr2,制备了两种新型一维 (1D) 配位聚合物 [Si(CH2SR)4}HgBr2]n (R = Me, 2a; R = Ph, 2b) CH2SR)4 (R = Me, 1a; R = Ph, 1b) 作为四齿硫醚配体。扩展结构是由连接单体 Si(CH2SR)4}HgBr2 单元的分子间 Hg-S 相互作用产生的,如使用单晶 X 射线衍射为 2a、b 建立的那样。两种化合物中 Hg 原子周围的有效配位最好被描述为扭曲的八面体。
