Abstract: The 1 : 1 reaction between the cyclodiphosphazane cis-{(o-MeOC6H4O)P(mu-(NBu)-Bu-t)}(2) ( 1) and AgOTf afforded one-dimensional Ag-I coordination polymer [Ag{mu-OTf-kappa 0,kappa 0}{mu-(o-MeOC6H4O)P(mu-(NBu)-Bu-t)-kappa P,kappa P}(2)](infinity) ( 2) containing bridging cyclodiphosphazane and trifluoromethanesulfonate (OTf) ligands. The 2 : 1 reaction of 1 and AgOTf leads to the formation of simple mononuclear complex [Ag{OTf-kappa 0,kappa 0}({(o-MeOC6H4O)P(mu-(NBu)-Bu-t)-kappa P}(2))(2)] (3) in quantitative yield. Reaction of 1 with AgCN produces a strain-free zig-zag coordination polymer [({(o-MeOC6H4O)P(mu-(NBu)-Bu-t)-kappa P, kappa P}(2))(2)Ag(NCAgCN)](infinity) (4) irrespective of reaction stoichiometry and conditions. In complexes 3 and 4 cyclodiphosphazanes coordinate to Ag-I centers in a monodentate fashion. Single crystal structures were established for the Ag-I polymers 2 and 4.
