Two new manganese-based phosphomolybdate compounds as electrochemical sensors for the highly sensitive trace determination of heavy metal Cr(vi) ions

Abstract

A convenient and sensitive method for the determination of heavy metal Cr(VI) ions is achieved. Here, two reductive polyoxometalate–based compounds, Mn2{Mn[Mo6O12(OH)3(H2PO4)(PO4)3]2}[H2(X–AP)]4 [X = 3 (1) or 4 (2), AP =...

A new {P4Mo6}-based complex as a highly efficient heterogeneous catalyst for the oxidation of alkylbenzenes under mild conditions

“…1b), where the Mn5–O bond length varies between 2.182 and 2.207 Å (Table S2†), which conforms to the normal range of Mn–O bonds. 42,43 The independent {Mn(P 4 Mo 6 ) 2 } is connected by mononuclear Mn4 and trinuclear Mn units (Mn1, Mn2, Mn3) to form a one-dimensional double-chain structure (Fig. 1c), in which mononuclear Mn4 exists in the six coordinated form, while trinuclear Mn is composed of two five-coordinated Mn atoms (Mn1, Mn3) and one six-coordinated Mn2 (Fig.…”

Two {CuI[P4Mo6]2}-Based Coordination Polymers Incorporating In Situ Converted Tetrapyridyl Ligands for Trace Analysis of Nitrofuran Antibiotics

“…Additionally, discrete structures assembled by weak interactions among POM-based architectures stand out due to their exposed active sites and potential hydrogen-bonding effect. , Reports indicate that hydrogen bonding can enhance electrochemical behavior by providing more mobile protons . The addition of nitrogen-containing ligands, such as thiazole, pyridine, and imidazole, to the system facilitates the formation of hydrogen bond interactions. , …”
