含类立方烷银(Ⅰ)簇的光致蓝光配位聚合物的原位溶剂热合成

A blue photoluminescent coordination polymer Ag₄Cl₄(dppe)₂]_n has been prepared solvothermally and characterized structurally. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of tetragonal, space group I4₁/a, a=b=1.936 03(6) nm, c=1.465 63(8) nm, V=5.493 5(4) nm³, Z=4, D_calcd=1.657 Mg·m^-3, μ=1.749 mm^-1. Reflections collected: 17 147, independent reflections: 3 247, R_int=0.021 1. Final R indices I> 2σ(I)]: R₁=0.044 8, wR₂=0.111 0. The structure of Ag₄Cl₄(dppe)₂]_n is a 3D-diamond highly symmetrical polymeric network containing Ag₄Cl₄ cubane-like clusters connected by 1,2-bis(diphenylphosphino)ethane (dppe). Each Ag₄Cl₄ cluster is composed of four silver and four chlorine atoms situated at alternate vertexes of a highly distorted cube with each silver atom being further coordinated to one phosphorus atom from a dppe ligand. The stripping of chloride ions from CHCl₃ provides the source for chlorine in the formation of Ag(Ⅰ) clusters. In addition, the emission spectrum of the complex 1 in solid state has been studied. CCDC: 288080.

The structure of Ag4Cl4(dppe)2]n is a 3D-diamond highly symmetrical polymeric network containing Ag4Cl4 cubane-like clusters connected by 1,2-bis(diphenylphosphino)ethane (dppe). Each Ag4C14 cluster is composed of four silver and four chlorine atoms situated at alternate vertexes of a highly distorted cube with each silver atom being further coordinated to one phosphorus atom from a dppe ligand.
