One-dimensional silver(i) coordination polymers containing cyclodiphosphazane, cis-{(o-MeOC6H4O)P(µ-NtBu)}2

Abstract

The 1 : 1 reaction between the cyclodiphosphazane cis-{(o-MeOC6H4O)P(µ-NtBu)}2 (1) and AgOTf afforded one-dimensional AgI coordination polymer [Ag{µ-OTf-κOO}{µ-(o-MeOC6H4O)P(µ-NtBu)-κPP}2] (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-κOO}({(o-MeOC6H4O)P(µ-NtBu)-κP}2)2] (3) in quantitative yield. Reaction of 1 with AgCN produces a strain-free zig-zag coordination polymer [({(o-MeOC6H4O)P(µ-NtBu)-κPP}2)2Ag(NCAgCN)] (4) irrespective of reaction stoichiometry and conditions. In complexes 3 and 4 cyclodiphosphazanes coordinate to AgI centers in a monodentate fashion. Single crystal structures were established for the AgI polymers 2 and 4.
