Adaptive Coordination Behavior of Bisphosphanylphosphanido‐Ligands Toward Group 2, 11 and 12 Metal Ions

Year: 2025

Type: article

Abstract: A series of alkaline earth metal complexes (Mg−Ba) with the anionic ferrocenylene‐bridged bisphosphanylphosphanide ligand [Fe(C5H4PC4H9)2P]− has been prepared by metalation of the corresponding bisphosphanylhydrophosphane (Fe(C5H4PC4H9)2PH). 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 μ2‐bridging of the phosphanide center has been observed. The value of the 1JPP coupling constant was found to be a good probe to track the coordination motif consistent with the situation in solid state.
