The anionic coordination polymer {K₂[Pt^II₂Ag^I₈(2,2′-bipyridine)₂(O₂CCF₃)₁₄]}_n

Abstract

The trimetallic compound catena-poly[dipotassium(I) [bis(2,2'-bipyridine)di-mu3-trifluoroacetato-dodeca-mu2-trifluoroacetato-diplatinum(II)octasilver(I)]], K2[Pt2Ag8(C2F3O2)14(C10H8N2)2], forms an extended structure in the solid state. Electrostatic interactions involving the K+ ions play a key role in the formation of the extended structure in three dimensions. The Ag(I) ions form one-dimensional coordination polymers, with alternating Ag2 and Ag6 units linked by CF3CO2- ligands. Pt...Pt interactions perpendicular to the one-dimensional polymerization axis provide another element of long-range order, and electrostatic interactions with K+ ions provide connectivity between adjacent polymeric structures.
