Organo‐Phosph(on/in)ate‐Bridged Dimers of Vanadium(IV) Complexes with the Kläui Ligand: Synthesis and Characterization

“…2.0 Å, one short vanadyl bond, and one long V···O interaction trans to the vanadyl. [5] The material crystallizes in the monoclinic space group P2 1 /c with two molecules per unit cell, but with disorder more pronounced than with any other crystallized species presented here. [20] The V···O trans to the V=O [here O1p, 2.2116 (13) (14) as is often observed.…”

“…The molecule crystallizes in the triclinic space group P1 with two molecules per unit cell. [5,10,11,21] (CpP OMe Co)VOCl·H 2 O (4) crystallizes in the monoclinic space group P2 1 /n with four molecules of 4 per unit cell. 2.0 Å, one short vanadyl bond, and one long V···O interaction trans to the vanadyl.…”

“…[1,2] Extended solids like vanadyl phosphate, VOPO 4 , and its hydrated forms are also widely employed as catalysts. [4][5][6] Typically we have employed the monoanionic tridentate oxygen donor ligand η 5 -cyclopentadienyltris(diethylphosphito-κ 1 P)cobaltate(III) first reported by Kläui, [CpP OEt Co] -. [4][5][6] Typically we have employed the monoanionic tridentate oxygen donor ligand η 5 -cyclopentadienyltris(diethylphosphito-κ 1 P)cobaltate(III) first reported by Kläui, [CpP OEt Co] -.…”

[4][5][6]8,9] To model the structure of the oxidation catalyst system VOPO 4 we have synthesized a series of organophosphonate/phosphonite/phosphate-bridged vanadyl dimers capped by this ligand.

Synthesis And Characterization Of A Series Of Vanadium(iv) Complexes With The Kläui Ligand

“…Otherwise, they will quickly oxidize to the vanadium(IV) species. Several vanadium(IV) molecules were synthesized by Anderson and co-workers in our group starting from vanadium(III) precursors (84)(85)(86)88). One example is shown in Scheme 6.…”
