Adaptive Coordination Behavior of Bisphosphanylphosphanido‐Ligands Toward Group 2, 11 and 12 Metal Ions
A series of alkaline earth metal complexes (Mg-Ba) with the anionic ferrocenylene-bridged bisphosphanylphosphanide ligand [Fe(C<sub>5</sub>H<sub>4</sub>PC<sub>4</sub>H<sub>9</sub>)<sub>2</sub>P]<sup>-</sup> has been prepared by metalation of the corresponding bisphosphanylhydrophosphane (Fe(C<sub>5</sub>H<sub>4</sub>PC<sub>4</sub>H<sub>9</sub>)<sub>2</sub>PH). The resulting complexes have been characterized by multinuclear NMR spectroscopy and SC-XRD. Furthermore, the closely related zinc phosphanide, and rare, mononuclear coinage metal phosphanides were synthesized and investigated for comparison. The range of coordination modes observed for the phosphanide ligand included mono-, bi-, and tridentate modi and their respective combinations, whereas no μ<sub>2</sub>-bridging of the phosphanide center has been observed. The value of the <sup>1</sup>J<sub>PP</sub> coupling constant was found to be a good probe to track the coordination motif consistent with the situation in solid state.
