Two novel self-interpenetrating 3D iron(II) coordination frameworks:synthesis, spectroscopic and structural characterizations with magnetic properties

摘要

Two novel self-interpenetrating 3D Fe(II) coordination frameworks namely {Fe(4,4′-bpy)[Ag(CN)]} () and {Fe(4,4′-bpy)[Ag(CN)][AgCN]} () have been synthesized and fully characterized. The 3D architectures and degree of interpenetration of these coordination frameworks were significantly affected by silver(I) cyanide species. The crystal structure of presents 4-fold interpenetrating 3D framework with 4,4′-bpy and [Ag(CN)] species. While, that of constructed by 4,4′-bpy and two different silver(I) cyanide species, AgCN and [Ag(CN)] resulting to 2-fold interpenetrating 3D framework. The stability and rigidity of both coordination frameworks are mainly supported dominantly by Ag ⋯ Ag interactions. Their magnetic properties exhibit high spin behavior.
