Synthesis, Spectrosopy and EXAFS of a Binuclear Complex of Ir(I): The First Example of a Bond Stretch Isomer?
Our research is concerned with potential bond stretch isomers in the [Ir2(dimen)4]2+ complex. The purpose of this summer?s research was three fold (1) to re-synthesize two salts of the iridium complex, which have two different Ir-Ir separations as determined by X-Ray crystallography, (2) in collaboration with the Synchrotron Accelerator Facility at Stanford University and the utilization of now Dr. Villahermosa?s original calculations as a guide carry out a series of Extended X-Ray Absorption Fine Structure (EXAFS) experiments on these two crystals, as well as a salvation of [Ir2(dimen)4]2+ to show conclusively whether this complex does indeed exhibit bond stretch isomerism, and (3) conduct molecular modeling calculations to determine the energy in terms associated with bending and twisting the dimen ligands.
