| Popis: | We report the synthesis, spectroscopy and X-ray structural characterization of seven new mixed alkyl-perfluoroalkyl silver tris(pyrazolyl)borate complexes with the general formula TpAg, where RF = CF3 or C2F5. The metal is partly encapsulated in a fluorine-rich environment and exhibits high Lewis acidity, allowing additional coordination by toluene (Tol), triphenylphosphine (PPh3), methyldiphenylphosphine (PMePh2) and triphenylphosphine oxide (OPPh3). A single-crystal X-ray analysis of the new data proposes a structural model that predicts interatomic distances and may rationalize the relative stability of members of this class of compounds. The electronic and steric effects of Tp substituents, combined with those of additional ligands, can lead to remarkably stable compounds, both in solution and the solid state, even when an ion particularly prone to reduction, such as silver(I), is involved. |
