In order to explore the chemistry of the bidentate ligand 2,2-dimethylpropane-1,3-diyl diisocyanide and to investigate the effect of counter-ions on the polymeric structure of (2,2-dimethylpropane-1,3-diyl diisocyanide)silver(I) complexes, the title polymeric compound, [AgI(C7H10N2)]n, was synthesized by treatment of 2,2-dimethylpropane-1,3-diyl diisocyanide with AgI. X-ray powder diffraction studies show, as expected, a polymeric structure, similar to the very recently reported Cl−and NO3−analogues [AgX(C7H10N2)]n(X= Cl−or NO3−). In the title structure, the AgIcentre is bridged to two adjacent AgIneighbours by bidentate 2,2-dimethylpropane-1,3-diyl diisocyanide ligandsviathe NC groups to form [AgCNCH2C(CH3)2CH2NC}]nchains. The iodide counter-ions crosslink the AgIcentres of the chains to form a two-dimensional polymeric [AgCNCH2C(CH3)2CH2NC}]I}nnetwork. This study also shows that this bidentate ligand forms similar polymeric structures on treatment with AgX, regardless of the nature of the counter-ionX−, and also has a strong tendency to form polymeric complexes rather than dimeric or trimeric ones.
