Crystal structure of poly[tetra-l2-cyanido- 1:2j8N:C-bis(dimethyl sulfoxide-1jO)- diargentate(I)iron(II)]

Abstract

In the title polymeric complex, [Fe{OS(CH3)2}2{Ag(CN)2}2], the FeII cation is located at an inversion centre and is coordinated by four cyanide (CN) anions and two dimethyl sulfoxide molecules in a slightly compressed N4O2 octahedral geometry, the AgI cation is C-coordinated by two CN anions in a nearly linear geometry. The CN anions bridge the FeII and AgI cations to form a twodimensional polymeric structure extending parallel to (102). In the crystal, the nearest Ag Ag distance between polymeric sheets is 3.8122 (12) A˚ . The crystal studied was a twin with a contribution of 0.2108 (12) for the minor component.
