Assembly of a Cyclic Dimer Silver(I) Complex Encapsulating Two BF4-Ions

The crystals with high quality forX-ray analysis were obtained by the vapor diffusion ofdiethyl ether into the DMSO solution of the precipitates.Crystal parameters and procedural information correspond-ing to data collection and structure refinements are given inTable 1. The geometric parameters of the complex are shownin Table 2.According to X-ray crystal structure analysis (Figure 1),the discrete cyclodimeric complex, [Ag(1)]
