A permanently porous, three-dimensional metal-organic material formed from zero-valent metal nodes is presented. Combination of ditopic m-terphenyl diisocyanide, [CNAr], and the d Ni(0) precursor Ni(COD), produces a porous metal-organic material featuring tetrahedral [Ni(CNAr)] 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 N-adsorption profile.
