摘    要:Introduction So far, considerable attention has been paid to mag-netic interaction between two different metal ions.1-3 As a potential bridging ligand, thiocyanate can coordinate to a harder metal center with N atom and softer ones with S atom at the same time, resulting in the formation of small ferromagnetic coupling.2 On the other hand, the Fe(III) atom is a good candidate as a hard acid and Ag(I) is a good candidate as a soft acid, so that the Fe(III) centers could be expected to conn…

Abstract:The Ag2S2 rings connect Fe(NCS)5(DMF)]2‐ (DMF=N,N‐dimethylformamide) octahedrons by bridging thiocyanates leading to a 3‐D Ag2Fe(SCN)5(DMF)]n framework. The Fe(III) atoms are in the octahedral geometry and Ag(1) atoms are in the distoned tetrahedral geometry. One‐dimensional Ag2S2‐S‐Ag2S2 wave‐like strand chains along the b‐axis and channels constructed from ten‐membered Ag2Fe(SCN)2S rings along the c‐axis feature the three‐dimensional framework. The Ag…Ag distance of 0.3103(1) nrn in Ag2S2 rings indicates weak Ag…Ag interaction. Such an Ag2S2‐S‐Ag2S2 chain in silver(I) complexes is unprecedented.
