The effect of bidentated phosphanes upon thiosaccharinate coordination in ternary silver and copper complexes is analyzed. Three solid silver and copper-diphosphanes complexes with thiosaccharinate as counter anion [Ag(tsac)(dppe)(CH₃CN)]ₙ (1), [{Cu(tsac)(dppe)}₂(μ-dppe)]·4CH₃CN (2) and Ag₂(tsac)₂(dppm)₃ (3) (tsac: thiosacharinate anion, dppm: bis(diphenylphosphanyl)methane, dppe: bis(diphenylphosphanyl)ethane) were synthesized and fully characterized by means of spectroscopic techniques (FTIR, UV–Visible, and ¹H, ³¹P and ¹³CNMR). The crystal structures of complexes 1 and 2 were solved applying single crystal X-ray diffraction techniques. Complex 1 shows a 1-D polynuclear arrangement with dppe molecules bridging Ag(I) centers. Complex 2 is built by dinuclear units with two chelating and one bridging dppe molecules.
