The purpose of the present contribution is to illustrate how to design and grow crystals of POMOFs based on POM-hybrid linkers with lanthanide ions as nodes. Thus, the MnIII-centered Anderson–Evans polyoxometalate (Mn-A-E-POM) was functionalized with 4-(((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)methyl)benzoic acid (H4L) to afford the hybrid inorganic–organic POM [N(n-C4H9)4]4[(MnMo6O18)(HL)(L)] (1), which in turn reacts with lanthanide salts and yields two three-dimensional frameworks with the general formulas Ln(DMF)6Ln(DMF)5Ln3(DMF)10[(MnMo6O18)(L)2]3·xDMF (2; Ln = La–Nd) and [Ln(DMF)4(H2O)]2[Ln3(DMF)6][(MnMo6O18)(L)2]3·xDMF (3; Ln = Y, Sm–Lu). The differentiation in these two families results from the lanthanide contraction. The crystallization process is crucial for obtaining these two families in a bulk pure phase. Family 2 can be obtained by stirring, while for family 3 the less energy demanding layering method proved to be the most efficient pathway. Notably, the change in the ionic radii causes a change in space group (from P21 (family 2) to P21/c (family 3); however, the topology of the frameworks is unaffected.

“…Furthermore, POMCPs based on Keggin-type unit represent over 50% of the described members of this family [ 41 , 42 ]. In addition, one should stress that POMCPs present a lot of different and attractive applications in: photocatalysis [ 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ], electrocatalysis [ 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 ], magnetism [ 69 , 70 , 71 , 72 , 73 , 74 ], and photoluminescence [ 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 ].…”

Tungsten and Molybdenum Heteropolyanions with Different Central Ions—Correlation between Theory and Experiment

2021

Density functional theory calculations were carried out to investigate the electronic structures of Keggin-typed [XMo12O40]n− and [XW12O40]n− anions with different heteroatoms (X = Zn2+, B3+, Al3+, Ga3+, Si4+, Ge4+, P5+, As5+, and S6+). The influence of solvent on redox properties of heteropolyanions was discussed. For [XW12O40]n− systems two linear correlation: first, between the experimental redox potential and energies of LUMO orbital; and second, between the experimental redox potential and total energy interaction (calculated between internal tetrahedron (XO4n−), and rest of Kegging anion skeleton, (W12O36)) were designated. Taking into account the similarity of XW12O40n− and XMo12O40n− systems (in geometry and electronic structure), the estimated redox potential of molybdenum heteropolyanions (with X being p block elements) in different solvent were proposed.

“…Furthermore, the determination of oxalate content in food is also important since the low oxalate diet is sometimes necessary for the treatment. Several methods developed in recent years to determine the concentration of oxalate include chromatography ( 14 ), chemiluminescence ( 15 ), amperometry ( 16 , 17 ), flow injection analysis ( 18 ), electrochemistry ( 19 ), capillary zone electrophoresis ( 20 ), and enzyme-based methods ( 21 ). However, most of these approaches require a high cost for the operation, special equipment, and long time for tedious preparation of the sample.…”

SUMMARYThe paper proposes a method that exhibits operational simplicity for the indirect spectrophotometric determination of oxalate ion. We developed Reactive Blue 4 (RB4) as a sensor by complexation with copper ion as a simple, inexpensive yet selective colorimetric chemosensing ensemble for the recognition of oxalate over other available competitive analytes via indicator displacement assay (IDA) in both solution (aqueous medium) and solid state (paper-based experiment). The addition of oxalate to RB4-Cu2+ complex changed the colour from sky blue to dark blue due to the regeneration of RB4 by the chelation of oxalate as the competitive analyte with Cu2+. The absorbance band increase is linear with oxalate concentration from 1.76 to 49.4 µmol/L with a detection limit of 0.62 µmol/L. This measurement mode did not show any influence of interferences (available anions and ascorbic acid). This approach eliminated the need for the separation stages, enzymatic multiple-step reactions, sample preparation, organic solvent mixture, chemical modifications and equipment developed to a high degree of complexity. The oxalate determination gave results in different real samples such as urine, mushroom and spinach, which demonstrated the applicability of the existing method. Furthermore, this colorimetric system can serve as IMPLICATION molecular logic gate using Cu2+ and oxalate (C2O42–) as inputs and UV-Vis absorbance signal as the output with potential monitoring applications.
