Abstract
Ag(h2-N-S)2(PF6), N-S = 1-methyl-2-(methylthiomethyl)-1H-benzimidazole, mmb (1) or 1-methyl-2-(tert-butylthiomethyl)-1H-benzimidazole, mtb (2), and Ag(m,h2-mmb)(m,h2-O2PF2) (3) were synthesized and characterized by x-ray crystallog. Long Ag-S ($\sim$2.70 \AA) and shorter Ag-N bonds ($\sim$2.23 \AA) are part of characteristically distorted tetrahedral coordination arrangements at the Ag(I) ions in 1 and 2. Unexpectedly, the comparison with Cu(h2-mmb)2(PF6) reveals a more tetrahedral and less linear coordination arrangement for the corresponding Ag species. 3 As obtained by hydrolysis of the PF6 ion or using AgPO2F2 exhibits bridging mmb and h2-difluorophosphate ligands in a chain-type structure. on SciFinder(R)
