hydrothermal conditions. By tuning the bis(tetrazole)-functionalized thioether ligands, compounds 1–4 exhibit Keggin-based bi-, tri- and mono-nuclear structures respectively, in which copper ion is +I oxidation state in compounds 1–2, and +II oxidation state in compounds 3–4. Compound 1 is composed of three moieties, [PW12O40]3− anion and two kinds of bi-nuclear subunits [CuI2(bmtm)3]2+ and [CuI2(bmtm)4]2+
摘要四种基于Keggin的化合物[CuI2(bmtm)3] 2·[CuI2(bmtm)4]·(PW12O40)2(1),(bmtm = 1,1'-双(1-甲基-5-巯基- 1,2,3,4-四唑)甲烷),[CuI3(bmte)3(PW12O40)](2)(bmte = 1,2-双(1-甲基-5-巯基-1,2,3,4 -四唑)乙烷),[CuII(bmtb)3(HPW12O40)](3)和[CuII(bmtb)3(HPMo12O40)](4)(bmtb = 1,4-双(1-甲基-5-巯基- (1,2,3,4-四唑)丁烷),已在水热条件下设计和合成。通过调节双(四唑)官能化的硫醚配体,化合物1-4分别显示出基于Keggin的双,三和单核结构,其中铜离子在化合物1-2和+ II中为+ I氧化态化合物3-4中的氧化态。化合物1由三个部分组成:[PW12O40] 3-阴离子和两种双核亚基[CuI2(bmtm)3]
