The reaction of Cu(CHCN) with 1-methyl-1,3-imidazolidine-2-thione {SCH(NMe)NH}, under aerobic conditions at room temperature, yielded an unusual one-dimensional coordination polymer, namely, -poly[[[(1-meth-yl-1,3-imidazolidine-2-thione-κ)copper(I)]-μ-(1-methyl-1,3-imidazolidine-2-thione)-κ :-copper(I)-μ-[3,3'-(sulfanedi-yl)bis-(1-methyl-1,3-imidazolidine-2-thione)]-κ ,','':,''] bis-(tetra-fluorido-borate)], {Cu(CHNS)(CHNS)} or [Cu(κ: -N-S-N- )(κ: -NH)(κ: -NH)] (BF) [ = SC H(NMe)NH] with sulfur-bridged {Cu S} central cores. The generated bis-(1-methyl-1,3-imidazolidinyl-2-thione) sulfide [{SCH(NMe)NSN(NMe)CHS; abbrev. -N-S-N- ] ligand, in combin-ation with 1-methyl-1,3-imidazolidine-2-thione ( -NH) ligands, construct this coordination polymer. Each Cu ion is bonded to four sulfur donor atoms in a distorted tetra-hedral geometry and the formation of this polymer solely by sulfur donor atoms with {Cu S} central cores, is the first such example in copper-heterocyclic-2-thione chemistry.
在室温有氧条件下，Cu(CHCN) 与 1-甲基-1,3-咪唑烷-2-硫酮 {SCH(NMe)NH} 反应，生成了一种不寻常的一维配位聚合物，即 -聚[[[(1-甲基-1,3-咪唑烷-2-硫酮-κ)铜(I)]-μ-(1-甲基-1,3-咪唑烷-2-硫酮)-κ :-铜(I)-μ-[3,3'-(硫烷二亚基)双-(1-甲基-1,3-咪唑烷-2-硫酮)]-κ,','':,'']双-(四氟硼酸根)]，{Cu(CHNS)(CHNS)} 或 [Cu(κ: -N-S-N- )(κ: -NH)(κ: -NH)] (BF) [ = SC H(NMe)NH]，其具有硫桥连的 {Cu S} 中心核。生成的双-(1-甲基-1,3-咪唑烷-2-硫酮基)硫化物 [{SCH(NMe)NSN(NMe)CHS; 缩写为 -N-S-N- ] 配体，与 1-甲基-咪唑烷-2-硫酮 ( -NH) 配体结合，构建了这种配位聚合物。每个 Cu 离子以扭曲的四面体几何构型与四个硫供体原子键合，并且仅由具有 {Cu S} 中心核的硫供体原子形成这种聚合物，这在铜-杂环-2-硫酮化学中是首例。
