A permanently porous, three-dimensional metal–organic material formed from zero-valent metal nodes is presented. Combination of ditopic m-terphenyl diisocyanide, [CNArMes2]2, and the d10 Ni(0) precursor Ni(COD)2, produces a porous metal–organic material featuring tetrahedral [Ni(CNArMes2)4]n structural sites. X-ray absorption spectroscopy provides firm evidence for the presence of Ni(0) centers, whereas gas-sorption and thermogravimetric analysis reveal the characteristics of a robust network with a microdomain N2-adsorption profile.

零价金属中心结晶协调网络:用3维的Ni(0)框架的形成三联苯Diisocyanides

介绍了一种由零价金属节点形成的永久多孔的三维金属有机材料。双中心的组合三联苯diisocyanide,[CNAR Mes2 ] 2,和d 10的Ni(0)前体的Ni(COD)2,产生设有四面体[镍(CNAR多孔金属-有机材料Mes24 ] ñ结构位点。X射线吸收光谱学为存在Ni(0)中心提供了有力的证据,而气体吸收和热重分析则显示了具有微区N 2吸收分布的坚固网络的特征。
