Polyanionic Imido-P(V) Ligands: From Transition Metal Complexes to Coordination Driven Self-Assemblies.
Sarkar M, Rajasekar P, Jose C, Boomishankar R. Sarkar M, et al. Chem Rec. 2022 Mar;22(3):e202100281. doi: 10.1002/tcr.202100281. Epub 2021 Dec 27. Chem Rec. 2022. PMID: 34962082 Review.
The chemistry of the imido-anions of the main group elements has been studied for more than three decades. The imido (NR)(-) group is isoelectronic to the oxo (=O) group and can coordinate with metal ions through its lone pairs of electrons. ...

(tert-Butyl-imido)bis-(eta-cyclo-penta-dien-yl)pyridine-zirconium(IV).
Kaleta K, Arndt P, Spannenberg A, Rosenthal U. Kaleta K, et al. Acta Crystallogr Sect E Struct Rep Online. 2010 Aug 28;66(Pt 9):m1180. doi: 10.1107/S1600536810033556. Acta Crystallogr Sect E Struct Rep Online. 2010. PMID: 21588566 Free PMC article.
The zirconium atom is coordinated in a distorted tetra-hedral geometry by two cyclo-penta-dienyl ligands, a pyridine ligand, and a tert-butyl-imido ligand via a Zr=N double bond. The tert-butyl group is disordered over two positions in a 0.634 (5):0.366 (5) ratio....
