Self-assembly of one- and two-dimensional coordination polymers with quinonoid backbones featuring coinage metals as nodes

Abstract

We report the use of the organometallic linker [Cp*Ir(η 4-benzoquinone)] (1b) L Ir to construct novel supramolecular one- and two-dimensional (ID and 2D) coordination polymers {[Cu 2(L Ir) 2(CH 3CN)(OTf) 2][L Ir](OTf)} n (3) and {[Ag 2(CH 3CN) 2]-[L Ir] 2(OTf) 2} n (4). Complex 3 formed a zigzag chain of Cu(I) and Cu(II) centers connected through irido-quinonoid backbones, while complex 4 exhibited argentopilic Ag⋯Ag d 10-d 10 contacts at d = 3.638 Å and C⋯H/π interactions between the ID chain neighbors. © 2007 American Chemical Society.
