Abstract:
The complexes [Ag 12 (Spz) 12 (N‐triphos) 2 ][Ag 3 (Spz) 3 (N‐triphos)] 2 · (DMF) 6 ( 1 ) and [Ag 18 (Spz) 12 (N‐triphos) 4 (CF 3 CO 2 ) 6 ] ( 2 ) were synthesized and structurally characterized by X‐ray diffraction [HSpz = pyrazine‐2‐thiolate, N‐triphos = tris((diphenylphosphanyl)methyl)amine]. The central [Ag 6 ] ring with chair‐conformation in 1 and the ideally octahedral [Ag 6 ] cluster core in 2 are both stabilized by the tripodal building units of neutral [Ag 3 (Spz) 3 (N‐triphos)] compound. The Ag ··· Ag distances of the [Ag 6 ] moieties in 1 and 2 are 3.07 and 2.81 Å, respectively, exhibiting intermetallic interactions, which can enhance the stability of [Ag 6 ] conformations. In addition, the π ··· π interactions between parallel pyrazine rings could impose on the building and the Ag ··· Ag interactions of these Ag–S clusters.
