Colourless crystals of the 1,4,8,11-tetraazacyclotetradecane (cyclam) silver(I) thiocyanate complex [Ag(SCN) · (C10H24N4)1/2] were obtained by diffusion of a solution of cyclam in ethanol into an aqueous solution of K[Ag(SCN)2], The crystals are tetragonal, space group P42/n, Z = 8, a = b - 1256.0(4), c = 1185.5(9) pm. 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.
