Poly[(μ2‐2,2‐dimethylpropane‐1,3‐diyl diisocyanide)‐μ2‐nitrato‐silver(I)]: a powder study

In order to investigate the effect of counter‐anions on the polymeric structure of (2,2‐dimethylpropane‐1,3‐diyl diisocyanide)silver(I) complexes, the novel title polymeric compound, Ag(NO₃)(C₇H₁₀N₂)]_n, has been synthesized. The crystal structure was determined by simulated annealing from X‐ray powder diffraction data collected at room temperature. The current structure is similar to the recently reported structure of the analogue with chloride replacing nitrate. This study illustrates that both the chloride and nitrate complexes crystallize in the orthorhombic system in the Pbca space group with one monomer in the asymmetric unit, and also gives a strong indication that the counter‐anion does not have a considerable effect on the polymeric structure of the complex. The Ag centre lies in a distorted tetrahedral environment and is bonded to two 2,2‐dimethylpropane‐1,3‐diyl diisocyanide ligands to form chains. The nitrate anions crosslink the Ag centres of the chains to form a two‐dimensional polymeric network structure.
