The SCN groups act as μ3 ligands, the S atoms of two SCN groups bridge two neighbouring Ag ions, which are only 297.5 pm apart, forming butterfly-like Ag2S2 moieties, the N atoms of the SCN groups form bonds to Ag atoms of adjacent Ag2S2 moieties. Two Ag2S2 units are again connected by cyclam molecules which act as two-dentate bridging ligands. Thus a complicated three-dimensional “supramolecular” structure results.de540 Chemie und zugeordnete Wissenschaften1,4,8,11-TetraazacyclotetradecaneSilver(I) Thiocyanate complexcrystal structureArticle1865-7117
