Synthesis and characterization of <sup>15</sup> N-labeled tetranuclear Ir complexes <i>via</i> Li <sub>2</sub> C <sup>15</sup> N <sub>2</sub>
The synthesis of <sup>15</sup>N-labeled organometallic complexes is challenging due to limited suitable <sup>15</sup>N-labeled precursors. Herein, we report the preparation of a <sup>15</sup>N-labeled tetranuclear iridium complex, 15N-1, from Li<sub>2</sub>C<sup>15</sup>N<sub>2</sub>, with nitrogen atoms originally from <sup>15</sup>N<sub>2</sub> gas. Mono-methylation and single-electron oxidation of 15N-1 yield the corresponding ate complexes, 15N-2 and 15N-3. These complexes were characterized by <sup>1</sup>H, <sup>13</sup>C, and <sup>15</sup>N NMR spectroscopy and X-ray diffraction.
