Isolation and Structures of One- and Two-Dimensional High-Nuclearity Silver(I) Clusters from a Silver Propane-2-thiolate Chain

Abstract

Interaction of [Ag(SiPr)]n and CF3CO2Ag in methanol led to isolation of a one-dimensional chain silver cluster {[Ag24(μ-OH2)2(μ-O2CCF3)10(η1-O2CCF3)2(μ4-SiPr)12(OH2)4(HOCH3)6]·(H2O)4}n (1). Reaction of [Ag(SiPr)]n and Et4N·I in dimethylformide gave a tubular cluster [Ag36(μ8-I)6(μ3-SiPr)30]n (2). Treatment of a mixed suspension of [Ag(SiPr)]n/AgI in methanol with HSiPr in the presence of Et3N resulted in formation of a two-dimensional anionic cluster {(HNEt3)4[Ag36(μ2-I)4(μ3-I)8(μ4-I)12(μ3-SiPr)16]}n (3). Structures of three clusters were established by single crystal X-ray diffraction and their solid ultraviolet properties were also investigated. Three polymeric frameworks of high-nuclearity silver(I) thiolate clusters have been isolated employing [Ag(SiPr)]n as a starting material and their structures were characterized by single-crystal X-ray diffraction.
