Reactions of (Et(4)N)[TpWS(3)] [Tp is hydridotris(3,5-dimethylpyrazol-1-yl)borate] with CuSCN in MeCN in the presence of melamine afforded the title neutral dimeric cluster [Cu(4)W(2)(C(15)H(22)BN(6))(2)(NCS)(2)S(6)(C(2)H(3)N)(2)] or Tp*W(μ(2)-S)(2)(μ(3)-S)Cu(μ(2)-SCN)(CuMeCN), which has two butterfly-shaped [TpWS(3)Cu(2)] cores bridged across a centre of inversion by two (CuSCN)(-) anions. The S atoms of the bridging thiocyanate ligands interact with the H atoms of the methyl groups of the Tp units of a neighbouring dimer to form a C-H···S hydrogen-bonded chain. The N atoms of the thiocyanate anions interact with the H atoms of the methyl groups of the Tp* units of neighbouring chains, affording a two-dimensional hydrogen-bonded network.
在三聚氰胺存在下,(Et(4)N)[TpWS(3)] [Tp为氢三(3,5 - 二甲基吡唑 - 1 - 基)硼酸酯]与CuSCN在乙腈中反应,得到标题中性二聚簇[Cu(4)W(2)(C(15)H(22)BN(6))(2)(NCS)(2)S(6)(C(2)H(3)N)(2)]或Tp*W(μ(2)-S)(2)(μ(3)-S)Cu(μ(2)-SCN)(CuMeCN),它具有两个蝶形的[TpWS(3)Cu(2)]核,由两个(CuSCN)(-)阴离子在一个反演中心桥连。桥连硫氰酸酯配体的S原子与相邻二聚体Tp单元甲基的H原子相互作用,形成C - H···S氢键链。硫氰酸根阴离子的N原子与相邻链Tp*单元甲基的H原子相互作用,形成二维氢键网络。
