Abstract M=E/M≡E multiple bonds (M = transition metal, E main group element) are of significant fundamental scientific importance and have widespread applications. Expanding the ranges M represents grand challenges for synthetic chemists will bring new horizons chemistry. There been reports majority metals, even some actinide metals. In stark contrast, as largest subgroup in periodic table, rare-earth metals (Ln) were scarcely involved Ln=E/Ln≡E bonds. Until recently, there a few examples monometallic alkylidene, imido oxo complexes, featuring Ln=C/N/O What absence phosphinidene complexes with Ln=P Herein, we report synthesis structure namely scandium phosphinophosphinidene complexes. Reactivity is also mapped out, appears to be easily tuned by supporting ligand.
