Coinage metals ternary tiosaccharinates: Synthesis, characterization and crystal structures of [Ag(tsac)(dppe)(CH3CN)]n and [{Cu(tsac)(dppe)}2(μ-dppe)]·4CH3CN

Abstract 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)(CH 3 CN)] n ( 1 ), [{Cu(tsac)(dppe)} 2 (μ-dppe)]·4CH 3 CN ( 2 ) and Ag 2 (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 1 H, 31 P and 13 CNMR). 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.
