文摘
Reaction of Ag6(tsac)6 (tsac− = thiosaccharinate anion) with PPh3 and 2,2′-bipyridine (bipy) ligands give rise to three new silver-thiosaccharinate complexes, [Ag(tsac)(PPh3)3], [Ag4(tsac)4(PPh3)3] , and [Ag2(tsac)2(bipy)2]. Their crystal structures established by single-crystal X-ray diffraction and IR spectroscopic characterizations are reported here. In each complex a singular coordination mode for the thiosaccharinate ligands is observed. The most important features of the different coordination modes of the thionates are discussed.
