Dinuclear Oxomolybdate(V) Species with Oxalato and Pyridine Ligands Revisited: cis/trans Isomerization of [Mo₂O₄(η²‐C₂O₄)₂(R‐Py)₂]^2– (R‐Py = Pyridine, Alkyl‐Substituted Pyridine) in Water Evidenced by NMR Spectroscopy

Syntheses and a Solid State Structure of a Dinuclear Molybdenum(V) Complex with Pyridine

“…The dihedral angle between the two Mo(μ 2 -O) 2 planes is by ca . 10° smaller than the angles observed in a series of oxalato complexes of the [Mo 2 O 4 (η 2 -C 2 O 4 ) 2 (R-Py) 2 ] 2− (R-Py = alkyl-substituted pyridine) type [16]. A distorted octahedral coordination of each metal centre of the {Mo 2 O 4 } 2+ core is completed by a chloride at 2.452(2)−2.477(2) Å for 1 and at 2.453(1)−2.466(1) Å for 2 and a pair of pyridine ligands with two distinctly different bond lengths.…”

One pot-synthesis of the fourth category of dinuclear molybdenum(VI) oxalate series: Structure and study of thermal and redox properties

“…4-EtPy = 4-ethylpyridine. 3.5-Lut = 3.5-lutidine) [10][11][12]. Each metal ion is coordinated by a terminal oxo ligand, a monochelating oxalate and a L ligand.…”

Hydrothermal synthesis, crystal structure and properties of a 3D-framework polyoxometalate assembly: [Ag(4,4′-bipy)](OH){[Ag(4,4′-bipy)]2[PAgW12O40]}·3.5H2O

“…To date, many zerodimensional (0D) discrete clusters [2][3][4][5] and 1D chains [4][5][6][7][8][9][10][11][12][13][14][15][16] have been reported. Recently, a few 2D layers [4,5,[13][14][15][16][17][18][19][20][21][22] and 3D frameworks [17][18][19][23][24][25] have also been synthesized. Exploring high-dimensional open frameworks based on POMs with metal-organic moieties still remains a challenge.…”

“…The use of polyoxometalates (POMs) as discrete building blocks for the syntheses of extensive inorganic-organic hybrid materials has attracted considerable interest in recent years [15][16][17][18][19][20][21][22][23][24][25][26][27][28]. The most common observed geometries of POM anionic clusters are the Keggin and Dawson heteropolyanions.…”
