title: Crystal structure of poly[tetra-μ2-cyanido-1:2κ8N:C-bis-(dimethyl sulfoxide-1κO)diargentate(I)iron(II)].
abstract: In the title polymeric complex, [Fe{OS(CH3)2}2{Ag(CN)2}2], the FeIIcation is located at an inversion centre and is coordinated by four cyanide (CN-) anions and two dimethyl sulfoxide mol-ecules in a slightly compressed N4O2octa-hedral geometry, the AgIcation is C-coordinated by two CN-anions in a nearly linear geometry. The CN-anions bridge the FeIIand AgIcations to form a two-dimensional polymeric structure extending parallel to (102). In the crystal, the nearest Ag⋯Ag distance between polymeric sheets is 3.8122 (12) Å. The crystal studied was a twin with a contribution of 0.2108 (12) for the minor component.
