| Abstract |
|
Metal phosphonates are an important class of compounds with applications in chemistry and material science. Despite an intense amount of research over the last few decades, the solution characterization of these species remains limited owing to poor solubility in common organic solvents. This article describes the synthesis, characterization, and reactivity of a rare class of organosoluble metal phosphonate complexes. The synthesis of Ag[P(O)(OC8H17)2] is straightforward and can be accomplished in a single three-hour laboratory period with minimal preparation. To the best of our knowledge, Ag[P(O)(OC8H17)2] exhibits the largest 1JAgP coupling constants (107Ag, 109Ag) ever reported, which clearly establishes that the bonding mode of the phosphonate fragment is through phosphorus and not through oxygen.

 Caution! | | Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations. |
