摘要：

Ag(CF3SO3) was reacted with the ligand alpha-(4-pyridyl)benzhydrol (LOH) in order to build a mixed organic/inorganic analogue of wheel-and-axle diols. In the resulting [Ag(LOH)(2)(CF3SO3)(CH3CN)] complex, the metal is four-coordinate, with two pyridines trans each other and a triflate and an acetonitrile group completing a sawhorse geometry. The main structural motif is based on the strongest and most directional tectons, the coordination bond Ag-O and the hydrogen bonds -OH...O-S-O...HO- Secondly, the sixfold phenyl embrace, CH3...pi, CH3...CF3 and Ag...F tectons also direct the crystal assembly. A new synthon originating from the combination of the S-O...HO-, the pi...CH3 and the CH3...CF3 individual tectons is identified. The structural roles of the anion and of the solvent are discussed.
