Discrete and polymeric organometallic-organic assemblies based on the diarsene complex [(Cp)2Mo2(CO)4(μ,η2-As2)], AgPF6 and N-donor organic molecules†
Abstract
Three-component reactions of the organometallic diarsene complex [Cp2Mo2(CO)4(μ,η2-As2)] (B) (Cp = C5H5) with AgPF6 in the presence of different N-donor linkers are presented. Depending on the organic linker used, discrete [{(η2-B)2Ag}2(L1)][PF6]2 (1) and [{(η2-B)2Ag}2(L2)][PF6]2 (2) organometallic-organic hybrid assemblies and polymeric [{(η2-B)Ag}(L3)]n[PF6]n (3), [{(η1:η2-B)2(CH3CN)2Ag2}(L4)]n[PF6]2n (4), [{(η1:η2-B)2(CH3CN)2Ag2}(L5)]n[PF6]2n (5) and [{(η1:η2-B)2(η1:η1-B)Ag2}(L5)]n[PF6]2n (6) ones are obtained. 4–6 possess unique structures in which Ag⋯Ag interactions occur.
