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(I) atoms are in the distorted 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) nm in Ag2S2 rings indicates weak Ag…Ag inter-action. Such an Ag2S2-S-Ag2S2 chain in silver(I) complexes is unprecedented.
