Synthesis and characterization of four cubical molybdenum(V) tetramers and their catalytic properties for the epoxidation of cis-cyclooctene using H2O2

Photo-redox reactivity of titanium-oxo clusters: mechanistic insight into a two-electron intramolecular process, and structural characterisation of mixed-valent Ti(iii)/Ti(iv) products

“…S21–25†). 42,43 The structures of 4 and 5 relate to other phosphinate supported heterocubane clusters with a M 4 (μ 3 -O 4 ) core (M = V, Mn, Mo, In, Sn, W) that have been previously reported;42,44–48…”

Syntheses and Structures of Three Complexes of Formulas [L3Co(μ2-O2P(Bn)2)3CoL′][L″], Featuring Octahedral and Tetrahedral Cobalt(II) Geometries; Variable-Temperature Magnetic Susceptibility Measurement and Analysis on [(py)3Co(μ2-O2PBn2)3Co(py)][ClO4]

“…Our interest in the complexes reported herein stems from our discovery that the dibenzylphosphinate ligand stabilizes tetrameric clusters such as [V 4 O 8 ] 4+ , [Mo 4 O 8 ] 4+ , and [W 4 O 8 ] 4+ . − Previous research reacting phosphinate ligands and cobalt have resulted in polymeric species. − In an extension of this work to prepare clusters of cobalt(III) oxides or hydroxides, we find that this ligand affords dinuclear clusters of the form [L 3 Co(μ 2 -O 2 P(CH 2 C 6 H 5 ) 2 ) 3 CoL′][L″]. Dark-blue crystals of [(py) 3 Co(μ 2 -O 2 PBn 2 ) 3 Co(py)][ClO 4 ] ( 1 ) were isolated first from an ethanol solution consisting of a mixture of Bn 2 PO 2 K, Co(ClO 4 ) 2 ·6H 2 O, pyridine (py), and H 2 O 2 .…”

Synthesis and Crystal Structures of Dioxomolybdenum(vi) Complexes Derived From Similar Benzohydrazone Derivatives With Catalytic Property

“…The coordination chemistry of dioxomolybdenum complexes with multidentate ligands has received considerable attention in recent years for their catalytic properties [1][2][3][4] and versatile structures. [5][6][7] Benzohydrazone derivatives are a kind of special Schiff bases which have been used as interesting ligands in coordination chemistry.…”
