Comprehensive coordination chemistry of iminophosphonamides

The iminophosphonamide [R₂P(NR′)₂]⁻ ligand is an analog of phosphate (R₂PO₂⁻), replacing its oxygen atoms with two amide groups. This review aims to provide the first comprehensive report on coordination chemistry dealing with iminophosphonamide ligands, focusing on the s-block, p-block, transition, and f-block metals. In particular, this monoanionic ligand's coordination mode and reactivity with the metal centers are discussed. The last section of the review is dedicated to the reported chiral iminophosphonamine ligands and corresponding metal complexes.
